AFR 220cc RUNNERS 65cc CHAMBERS ELIMINATOR ALUMINUM HEADS. This sale is for a full y assembled set of heads (2 heads).

The springs in this setup are to operate with Solid 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. The information below pertains to our testing with the AFR 210 heads. This sale is for the a set of 220cc heads setup for solid roller cams.

From what we have seen on the flow charts the 220cc heads do slightly edge out the 210's but not by much. We suggest using the 220cc heads on very aggressive setups coupled with cams in the 600 lift or more range, with higher amounts of duration than what is common in most street rods. These heads will most likely prevail when ran hard. We have not done any testing yet on the 220's but they are sure to make excellent power.

These heads may be on the larger than needed side for most hyd. Roller cam builds, but should you ever decide to increase your cam and or cubic inch on your engine, you would not be out growing the 220cc heads for certain.

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 chosen 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 421,427, and 434's. Engines in the 10:1 to 10.5:1 compression range, give or take. We also did an aggressive 406 build with the 210 heads.

Normally we use the 195cc heads on the 406 but found the 210's suitable due to the cam size of this one particular engine. 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 ads.

If you're 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.

Comp Cams SBC Xtreme Energy Step Nose Hydraulic Roller Camshafts. These particular heads are for a solid roller setup, not a hyd.

The dyno info below is just to give you an idea of what power may be obtained from these heads with a given cam size. Official Dyno report on our 434 engine with this cam, single plane intake, 1.6 rockers, Brawler 950 carburetor, AFR heads, and an MSD distributor. 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 outsourced 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. Not compatible with self-aligning rocker arms.

Number of Springs Per Valve. Outside Diameter of Outer Spring (in). Rocker Arm Nut Thread Size. 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. We are not responsible for collateral damage caused by the use of this product.
