AFR 165cc SBF Street Cylinder Head

The Small Port, High Velocity, Emission Legal Torque Monster

For the ultimate small block Ford street car, you’ve got to use AFR’s all new 165cc emissions legal cylinder heads. Unlike some aftermarket heads, AFR’s 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 and 69cc exhaust ports, AFR’s 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 number 1402. Note: 1986 5.0L must have piston notched for clearance.

Note:

Hydraulic roller cams typically experience valve float at 6000-6200 rpm because of their fast ramp rates. AFR suggests you upgrade your springs to AFR part #8047, 1.290 O.D. with higher spring pressures to reduce chances of valve float associated with rpm’s 6200 or higher.
