This is our new high performance cylinder head for Ford FE 390, 428 or 427 engines! Outflows and outpowers any traditional FE wedge head!
A serious upgrade for high powered applications - not just a replacement but a true performance upgrade! Covered extensively in numerous magazines, this new aluminum cylinder head makes a profound improvement in power and torque for any Ford FE engine. Our FE cylinder heads are significantly better than what competing suppliers offer. We use only name brand suppliers - no mystery metal, and only high quality domestic casting and machining. We have actually built these engines - hundreds of them - and do so every week in our own fully equipped engine shop, and run them on our own dyno to prove and refine the combinations.We can tell you what works, what fits, what does not, and can prove it with first hand experience. Many of our proven combinations can be viewed running on YouTube, and can be read about by visiting our FE engine tech forum, where complete write-ups and dyno data are available. This listing is for a set of complete heads ready for you to bolt on. Included in these heads are. Castings poured in a state of the art USA foundry that is well known for cylinder head casting expertise. Machined in the USA on top quality equipment, in a facility reknowned for quality. Thread inserts used on all critical locations. Bronze 11/32 valve guides are installed and honed - sized to your chosen valves. Hardened valve seats are installed, compatible with unleaded fuel, and have a 5 angle valve job. Intake port opening is similar to 427 medium riser and will work with most popular manifolds - only minimal port matching needed.
Intake airflow of +/-290 cfm as cast with a valve job & bowl blend - that's 30-40cfm better than competing heads. As cast port volume of only 180 cc (compared to 170cc for traditional heads) means that these are still very responsive and street oriented. Intake potential of nearly 370 cfm CNC ported (optional).
Exhaust ports are similar in position and size to 428 Cobra Jet. Normal header gaskets and headers will fit - works well in shock tower Mustangs or Fairlanes, as well as with Cobra side pipes. Has the 16 bolt exhaust pattern.Valve positions compatible with most OE or aftermarket pistons. Combustion chamber is 76cc, with a modern heart shape and a relocated spark plug for reduced spark advance and improved fuel tolerance. Revised water jackets to allow the new port and chamber design - you CANNOT modify an old style head to meet these goals. Dyno proven for durability and power. We ran the same pair of CNC ported heads in the Amsoil Engine Masters Challenge two years in a row, with plenty of street driving and drag race passes over the summer in between. The 433 inch engine made as much as 711 horsepower!
Complete street head package includes. Stainless steel swirl polished one piece valves - 2.200 intake and 1.680 exhaust. 4130 chrome-moly retainers, keepers, and spring locators. Double valve springs for a flat tappet or hydraulic roller cam - you specify. Bowl and port entry blending.
Dyno proven to deliver 500-600 horsepower with this valve job and bowl blending in pump gas combinations. Please be aware that these kits are assembled custom to your order and normally take between 3 and 4 weeks to deliver. This is very much reliant upon suppliers and if they run late - we will run late. If you have an issue PLEASE CALL - we want you to be satisfied! Warranties: We guarranty the parts to be as represented - - and damage free.
