AFR 238CC LS3 ENFORCER AS CAST (Select Options)

AFR's 238 LS3 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.  The AFR 238cc LS3 Enforcer is the first Enforcer casting with 100% AFR design.  With a smaller valve and port, this head outflows your OE LS3 casting, offering greater performance potential. This budget friendly head is perfect for your OEM engine operating below 6300 RPM. They come fully assembled with the identical components found in our higher end CNC ported cylinder heads; such as PAC Racing springs, viton valve seals, machined bead valve locks (not stamped), hardened spring seats, and our one piece 8mm 21-4N/21-8N Stainless Steel valves. They are available without any parts for the DIY. Sold as a single piece, 2 are required per engine.  Please see footnotes for additional information.
