AFR 238cc LS3 Enforcer Cylinder Heads

AFR's 238 LS3 Enforcer cylinder heads feature its 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. They are the first Enforcer castings with 100 percent AFR design. With a smaller valve and port, these heads outflow your OE LS3 casting by up to 20 cfm at low lifts, offering greater performance potential. The budget-friendly heads are perfect for your OEM engine operating below 6300 rpm. They come fully assembled with 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/21-8N stainless steel valves. They're available without any parts for DIY gearheads. Sold as a single piece; two are required per engine.
