LSX 210cc Enforcer Cyl Head 64cc As Cast Assem.

AFR's 210 LS1 Enforcer Cylinder heads feature Permanent Mold “As-Cast” Technology surfaces on the intake runners, exhaust runners, and combustion chambers, allowing for extremely accurate and repeatable port location/performance. This budget-friendly head is perfect for OEM engines operating below 6300 RPM. They come fully assembled with identical components found in 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. They are available without any parts for the DIY. Sold as a single piece, two are required per engine.
