If you need the world's finest high performance street/strip small block Ford heads, then check out AFR's 185cc emissions-legal Renegade Street cylinder heads (CARB E.O. #250-3). With lightweight 8mm, 2.020 in. intake valves and 1.600 in. exhaust valves, combustion chamber volumes of 58 or 72cc, and 68cc exhaust ports, AFR's 185cc Ford cylinder heads are designed for 302-351 c.i.d. engines operating from 1,500 to 6,500 rpm. A 3/4 in. thick head deck makes the AFR heads ideal for nitrous or blower applications. These heads will not accept rail rocker arms, and hardened push rods are required on models designed for stud mount rocker arms.
