AFR's 325cc BBC Enforcer cylinder heads feature their Permanent Mold "As-Cast" Technology surfaces on the intake runners, exhaust runners, and combustion chambers that allow for extremely accurate and repeatable port location/performance. These budget-friendly heads are perfect for your 509 to 540 cu.in. operating below 6,500 rpm. They come fully assembled with the identical components found in AFR's 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 seats, and AFR's one-piece 8mm 21 4N stainless steel valves.
