AFR 220cc Competition Renegade SBF Cylinder Heads, 72cc Chambers

AFR`s 220cc "Competition" heads feature 100% CNC ported intake, exhaust & chambers, A356 aluminum castings and high quality components throughout. This is AFR`s largest, best flowing head for the small block Ford. Recommended for race applications or radical "Pro Street" style builds. Component upgrade and machining options are available to customize AFR Heads to your specific build.







The Best 20° In-Line Head You Can Buy!

AFR's BRAND NEW 220cc Renegade Ford head is a fresh addition to the
lineup that adds quite a punch to our already formidable and proven
20° Ford Heads. These new 220cc heads flow a massive 340 CFM,
averaging an 11 CFM increase from .200-.800 lift over our previous
best in spite of its 5cc smaller intake runner. This is the best
small block Ford 20° inline head you'll find to provide huge
horsepower to out run your competition. With the largest intake and
exhaust runner volumes for our in-line Ford line up, these are the
ultimate for NMRA Renegade or Hot Street classes. With lightweight
8mm 2.100 intake valves and 1.570 exhaust valves these heads move
massive amounts of air. Combustion chamber volumes are available in
58cc or 72cc. 80cc exhaust ports and bolt pattern are raised .375
(3/8") higher than stock, this rarely affects header or chassis
fitment. AFR's new 220cc is the perfect choice for 347 through 427
CI windsor engines operating from 4500 rpm upwards. AFR's trademark
3/4" thick cylinder head deck makes them ideal for heavy nitrous or
blower applications.



Note:

2.100 valves will require aftermarket pistons notched for valve
clearance.
