Our NEW 165cc Renegade Ford is our re-engineered ground up redeisng of our already formidable and proven 20° Ford Heads. These new 165cc flow significantly more, averaging a 12 CFM increase from .200-.550 lift than our previous best 165cc. For the ultimate 289 or 302ci small block Ford street car, you've got to use AFR's all new 165cc emissions legal aluminum cylinder heads. Unlike some aftermarket heads, AFR's performance cylinder heads (CARB EO #250-3) fit all your stock components; no special parts are required! With lightweight 8mm 1.900 intake valves, 1.600 exhaust valve, combustion chamber volume of 58cc, and 68cc exhaust ports, AFR's new 165cc is perfect for 289 and 302 engines operating from idle to 6000 rpm. A 3/4" thick head deck makes it ideal for nitrous or blower applications. These heads will not accept rail rocker arms. Hardened push rods required on all applications. Note: 1986 5.0L must have piston notched for clearance.
