Mercury Marine 46820 Exhaust Manifold To Cylinder Head Gasket Genuine OEM product	$20.99~~$24.29~~ In stock 5+ in stock	Best	OEM MerCruiser gasket for GM big‑block V8s (7.4/8.1/8.2 L). The reflective silver face seen on the package and the overall reinforcement indicate a metal‑faced graphite composite that resists exhaust heat and maintains bolt preload through repeated heat cycles. Port and bolt‑hole geometry match factory manifolds precisely, reducing risk of edge burn‑through. Consistent user guidance from marine tech forums favors installing these dry (no RTV) and re‑torquing after a few heat cycles for long‑term sealing. Choose this when you want the exact fit and materials the engine was validated with, plus U.S. build and proven durability.

GLM Marine 33760 Gasket (2/Pack) - GLM Products (33760) (viewing this product) Aftermarket product	$30.40~~$38.00~~ In stock Only 1 remaining	Better	GLM’s 2‑pack mirrors the OEM in look and feel, with stainless‑laminated flexible graphite construction and a typical 1/16 in thickness—robust for exhaust heat and flange movement. Your note about slightly different reinforcement markings is consistent with a different manufacturer using the same sandwich design. Community experience shows these seal well when installed dry and torqued correctly; the material spec (graphite plus stainless foil) handles the ~1000°F exhaust environment and resists blowout. A solid aftermarket pick when you want OEM‑style materials and geometry at good value.
