200cc SBC Enforcer Cylinder Head

AFR’s 200cc SB Chevy Enforcer Cylinder heads feature our 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. This budget friendly head is perfect for your 350 to 400 cubic inch 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, racing springs, Viton valve seals, AFR adjustable guide plates, machined bead valve locks (not stamped), hardened spring cups and our one piece 8mm 21 4N stainless steel valves.

They are available in straight or angle plug and bare without any parts for the DIY racer. Sold as a single piece; 2 are required per engine. Please see footnotes for additional information.
