AFR 165 cc Aluminum Cylinder Heads for Small Block Ford

For the ultimate small block Ford street car, youve got to use AFRs all new 165cc emissions legal cylinder heads. Unlike some aftermarket heads, AFRs Ford head (CARB EO #250-3) fits all your stock components; no special parts are required! With 1.900 intake valves, 1.600 exhaust valve, and combustion chamber volumes of 58cc or 61cc, and 69cc exhaust ports, AFRs new 165cc Ford head is perfect for 289 and 302 engines operating from idle to 6000 rpm. A 3/4 thick head deck makes the AFR head ideal for nitrous or blower applications. Will not accept rail rocker arms. Hardened push rods required with part numbers 1400 and 1402. Note: 1986 5.0L must have piston notched for clearance.

The Non-Emission Legal heads come ready for the maximum street/strip Small Block Ford performance possible. They are not emissions legal. With the 165 coming with 1.900 intake and 1.600 exhaust valves and the 185 sporting 2.020 intake and 1.600 exhaust valves. Both heads feature 58cc or 61cc combustion chamber with 69cc exhaust ports. Both the 165cc and 185cc have available as an option nitrous or blower exhaust ports featuring either a 75cc ultra high flowing exhaust port. With AFRs trademark 3/4 thick head deck, its no problem handling that additional cylinder pressure. Each head is also drilled for the larger 1/2 head bolt hole for maximum head gasket retention as a standard feature of this serious race piece in street disguise.

Hydraulic roller cams typically experience valve float at 5800-6000 rpm because of their fast ramp rates. AFR suggests you upgrade your springs to AFR part #8032, 1.530 O.D. with higher spring pressures to reduce chances of valve float associated with rpms 6000 or higher.
