Afr 185cc Enforcer Sbf As Cast Cylinder Heads, 64cc Chambers, Small Valve

This is a BRAND NEW Enforcer AFR 185cc SBF As-Cast cylinder head with 64cc combustion chambers. AFR Part Number 1341. These heads use a smaller intake valve than the other Enforcer version so they are a direct fit for factory Ford 302 pistons.

AFR's 185cc SB Ford Enforcer Cylinder heads feature Permanent Mold “As-Cast” Technology surfaces on the intake runners, exhaust runners and combustion chambers that allows for extremely accurate and repeatable port location/performance. In addition, these heads utilize a 1.900” Intake valve and are compatible with OEM piston valve relief. This budget friendly head is perfect for your 302 to 363 Cubic Inch engine operating below 6000 RPM. They come fully assembled with the identical components found in our higher end CNC ported cylinder heads, such as ARP rockers studs, PAC Racing springs, Viton valve seals, AFR adjustable guide plates, machined bead valve locks (not stamped), hardened spring cups and ductile iron seats (not powdered metal) our one-piece 8mm 21 4N Stainless Steel valves. They are also available bare and without any parts for the DIY.
