Specifications:
The Most Powerful Bolt-On AFR's NEW 205cc Renegade Ford is a total ground up redesign of their already formidable and proven 20° Ford cylinder heads. The new 205cc flows an incredible 21 CFM more at peak flow while still averaging 7 CFM more from .200'' - .500'' lift over AFRs previous best 205cc runner. If you're looking for the most powerful standard type 20° small block Ford street/strip head, AFR's 205cc aluminum cyilnder head is your answer. With lightweight 8mm stem diameter, 2.080'' intake valves, 1.600'' exhaust valves this head moves tremendous volumes of air through conservative runner volumes, spelling big torque and horsepower numbers. Available with 58cc or 72cc combustion chamber volume. Exhaust ports and bolt pattern are raised .125'' higher than stock (this rarely affects header or chassis fitment), AFR's new 205cc is the ultimate choice for 367-427ci engines operating from 3500 RPM to 8000 RPM. AFR's trademark 3/4'' thick head deck makes them ideal for heavy nitrous or blower applications. . Installation Note: 2.080'' valves will require aftermarket pistons to be notched for valve clearance.
Street/Strip Cylinder Head Ever!
