AFR 210cc RUNNERS 65cc CHAMBERS ELIMINATOR ALUMINUM HEADS. FULLY CNC'd AIR FLOW RESEARCH. The springs in this setup are to operate with hydraulic roller cams up to.You may have noticed other sellers using a similar name offering similar products. These other sellers have capitalized on our name as we see it, and many customers searching for us will inadvertently find them, thinking we are one in the same company. There is only one Skip White. Our official company name is Skip White Performance. Please see the article in the lower part of this ad for a more detailed explanation. PICTURED ABOVE ARE OUR FULLY CNC'D AFR HEADS. The AFR heads are the best aftermarket cylinder heads in the world. Quality, performance, and reliability are excellent. Below is the flow chart on for the AFR 210cc heads.
The flow numbers speak for themselves. A cam in the 500 lift range on up to around 600 lift would be a very good match for these heads. As our company founder explains it, the results you experience with the AFR heads will vary greatly by what type setup you are running. Our engine combos we have dynoed are what most people have chose to use as far as cam and intake selection goes, and we have some of the results listed below.
The engines dynoed with the 210cc heads were mostly sbc 406 421,427, and 434's. In the 10:1 to 10.5:1 compression range, give or take. We also did a slightly aggressive 406 build with the 210 heads with a 580/600 hyd.
This particular 406 engine made 604 hp at around 6400 rpm. Normally we use the 195cc heads on the 406 but found the 210's suitable due to the cam size in the 406, coupled with a single plane intake and 1.6 rockers. All ran on pump gas. Our 421 through 434 engines add have a selection of four different cams and these engines all come with AFR heads and this has given us a great opportunity to see how they performed.We were able to test several different cam setups with these heads. This will give you an idea on what these heads are capable of with a given combination of cam, intake, rockers, and carb. This may also help you select a proper cam for your build.
We feel the 210cc AFR heads would perform very well on a medium to aggressive 421 427 or 434 build or a somewhat Pro-street 406. As mentioned, below is just an excerpt from our 421-434 adds. If you using a lower lift from those listed below then it would be fair to say the hp will drop, but not by much providing your lift and duration are somewhat close to any of the cams mentioned below. This will give you an idea of what kind of power to expect with these heads, and it can certainly help you choose a cam and intake. Please do understand that a cam is not included with the heads.This is just a guide to show what you may expect with a given combination when building your engine. Cam choice #1 with AFR 210cc heads. VALVE LIFT WITH 1.5 ROCKERS : INT. DURATION IN DEGREES : ADVERTISED - INT. This cam choice # 1 is somewhat aggressive in the 421 through 434 engines with the addition of the AFR 210cc heads.
We topped it off with a set of 1.6 rockers, and went with the Huricane single plane intake, added the Super Sucker plate, and produced an amazing 625 horse power at 6300 rpm with 550 lb ft of torque at 5200 rpm. This test was done our sbc 434 street rod engine on pump gas. The other engines mentioned have done very close to this with the same heads and cam package.Very good these numbers are for not having to run the rpm any higher than this. The horse power numbers are very accurate. We preformed the testing on our new Super Flo 902s dyno. No question the numbers are correct, as we have been spot on with all of our other dyno tests of engine combos that we knew what to expect from past dyno records. Cam choice #2 with the AFR 210cc heads.
LOBE SEPARATION ANGLE : 110 º. This cam choice (2) in the 421-434 engines with the AFR 210cc heads is the perfect all around setup for those wanting a very good bottom and mid range, yet still making excellent power at the top. This engine will use the same compression as the cam choice above. 30-35 hp with this cam. Bottem end power come in much sooner, and this cam smoothes out around 2200 rpm.
This cam will make it's peak power at approx. If your car is in the medium weight range or up to approx. 3,700 lbs, and your wanting slightly better streetability, then this is a good cam and head choice.You still want to keep the final gear ratio at. 323 but no more than a. 355 would be needed for great results on the street. Keeping the gear ratio on the tall side is more acceptable with this cam compared to the other choices mentioned above. You may choose 1.5 or 1.6 rockers with this cam, but we recommend the 1.5 rockers for better low end response.
This cam should be paired up with the dual plane Crosswind intake for better drivability. The single plane Hurricane can be used, but the dual plane will have much better bottom end and mid range response. Our test engine used the Single plane intake. The dual plane intake would drop peak power by about 15 hp over the single plane intake. Bottom end response would be better with the dual plane.
You can also expect a longer valve train life with this cam compared to the larger cam choices. Official dyno results on our 427 Stage 5.2 engine with this cam, AFR 210-75 Heads, a QuickFuel 750 carb, and a dual plane intake. An excerpt from our engine ad about our new dyno. As of 9/15/2013 we have completed installation of our brand new Super Flow 902S dyno. In the past we have out sourced our dyno work.
Needless to say it's been the best investment we have ever made. Every aspect of our engines can now be monitored, calibrated, tuned, and best of all see what combos make the best power, with consideration to drivability. One thing we have noticed is that the de-tuned engines with different cam and intake combos certainly do have less top end horse power as expected but the torque increase in the low rpm range is much greater than the higher horse power setup. This increase in torque down low is what you want if your sporting around on the street, rather than all out racing. The de-tuned version of our engines will also allow you to set the car up closer to stock and increase drivability to a very high degree.Throttle response is also noticeably better. One of the worst mistakes you can make building up an engine is to get a mismatched combination of parts. We know about combinations and how they work. Take a test drive in a car with over 400hp vs. A 300hp or less and you will then see what youâre missing. The exhaust sound under load is very pleasing. We are very pleased with everything about the AFR heads. Few if any of the others know much about the correct way to setup a set of cylinder heads.

I'm sure many of you have noticed there are 2 high performance engine builders in Kingsport, TN with similar names, leading to a great amount of confusion.We are Skip White Performance, NOT White Performance and Machine. Due to the name similarity, many customers looking for us online inadvertently find them, thinking we are the same company. There is no connection between the two companies. We don't have a problem with free enterprise (competition). However, when the competition builds their foundation on such things as a name similarity and their supposedly long history of being in business, then we think it's about time we set the record straight.
We have owned White Performance since 2003, with the exception of the machine shop, which was owned by Fred White at the time. Due to their limited production capability and many disagreements about the engine and head building process as well as workmanship, we opted to open a full scale machine shop of our own a few years later. Fred White began competing against us even though our contract had a non-compete clause in it. As our business grew, we opened a second, much larger warehouse and machine shop around 2011, located on Brookside Ln.By putting heart and soul in this company, we have become the number one street rod engine builder in the nation. This investor lacked any knowledge of this industry. They continue to use the White Performance & Machine name. Contrary to what is posted on their website, Fred White is no longer associated with the company in any way.
All in all, we have been in this business going on 17+ years. Skip White's passion has been owning and building street rods for 47 years on a personal level. The knowledge he has gained over time has allowed him to venture into this business and succeed to a very high level. The great pretenders continue capitalizing on our success due to the name similarity, but have been degrading our reputation.We have been getting calls nearly on a daily basis from people that now realize there are two shops in this town with very similar names. Customers complain of serious problems in getting their orders in a timely manner from them.
FAST FORWARD TO PRESENT DAY... We have become the largest street rod engine builder in the nation. 2-5 weeks, perhaps sooner, depending on the season.
