Specifications:
Small Port, High Velocity, AFR's NEW 165cc Renegade Ford cylinder head is a re-engineered version of their already formidable and proven 20° Ford cylinder head. This new 165cc flows significantly more, averaging a 12 CFM increase from .200-.550 lift than their previous best 165cc. For the ultimate 289 or 302ci small block Ford street car, you've got to use AFR's all new 165cc aluminum cylinder heads. Unlike some aftermarket heads, AFR's performance cylinder heads have been certified emission legal, CARB EO #250-3, and will fit all your stock components; no special parts are required! With lightweight 8mm 1.900'' intake valves, 1.600'' exhaust valve, 58cc combustion chambers, 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. .
Emission Legal Torque Monster!
Installation Note: 1986 5.0L must have piston notched for clearance.
