Product Description

AFR 165 SB Ford Renegade Cylinder Head (1399 - 58cc)

These AFR 165 Cylinder heads come ready for the maximum street/strip small block Ford performance possible when using a stock short block and OEM pistons. The 165 Renegade series cylinder heads feature lightweight 8mm valve stems with 1.900" intake and 1.600" exhaust valves.

The AFR #1399 heads have CNC ported 58cc combustion chambers, 165cc volume intake runners and 70cc ultra high flowing exhaust ports. These AFR small block Ford cylinder heads come fully CNC ported and ready to provide the maximum performance from your street/strip combination. Many performance features are included with this serious race piece in street disguise.

With AFR’s trademark 3/4” thick head deck, there's no problem handling the additional cylinder pressure of a turbo, blower or nitrous. Each 1399 casting is drilled for the larger 1/2” head bolts or studs for maximum head gasket retention. Adjustable push rod guide plates and stout rocker studs standard equipement. Stud mount rockers arms and hardened push rods required.

These AFR 1399 165cc performance heads are non-emissions legal. No heat riser or air pump holes for maximum street/strip performance.

NOTE: Today's more aggressive hydraulic roller camshafts typically experience valve float at 6000-6200 RPM because of their fast ramp rates. It is highly recommended to upgrade your springs to the optional higher pressure valve springs to reduce chances of valve float associated with 6200 or higher RPM.
