AFR 210cc LS1 Enforcer Cylinder Heads 1501

AFR 210cc LS1/LS2/LS6 Enforcer cylinder heads are available in standard and small bore applications. They feature 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. The budget-friendly heads are perfect for your OEM engine operating below 6,300 rpm. Fully assembled Enforcer models include the identical components found in AFR's higher end CNC-ported cylinder heads—such as PAC Racing springs, Viton ® valve seals, machined bead valve locks (not stamped), hardened spring seats, and one-piece 8mm 21 4N stainless steel valves. The heads are available without any parts for the DIY. Sold as a single piece, two heads are required per engine.Brand: Airflow Research (AFR)
