Specs At A Glance

Good To Know

Q: Do I need to resurface the heads before installing this gasket? A: The MLS gasket works best on a flat, clean deck surface; always check straightness and finish per manufacturer specs and resurface if out of tolerance.

Q: Can this gasket handle a 150-shot of nitrous on a 383? A: It is built for high-performance street engines, but for heavy power-adders a copper or dedicated race gasket may be required.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
