Cometic MLS gaskets are the preferred choice for serious engine builders because they accommodate minor surface imperfections, resist blowout under extreme cylinder pressures, and maintain their seal through repeated heat cycles. The valve relief pockets machined into this gasket ensure proper clearance for high-lift camshafts and oversized valves commonly used in performance builds.

This gasket is sold individually - order the quantity needed for your engine build. Proper surface preparation and torque specifications are critical for MLS gasket installation success.
