Cometic Cadillac L37/LD8 Northstar V8 .030in MLS Cylinder Head Gasket - 94mm Bore - RHS

If you're rebuilding the top end of your Cadillac L37 or LD8 Northstar V8, this Cometic Multi-Layer Steel (MLS) head gasket is a solid choice. It's specifically made to fit engines with a 94mm bore and is .030 inches undersize, designed for the right-hand side (RHS) of the engine. Cometic builds these gaskets with multiple layers of stainless steel, which gives them strength and helps them resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that seals exceptionally well, even with different block and head materials like aluminum to cast iron. You won't need any extra sealants with these gaskets; they're designed to seal perfectly on their own.

The multi-layer steel construction means these gaskets can handle the higher pressures found in performance-oriented engines. The embossed layers and Viton coating work together to create a strong seal that can withstand the shearing forces between dissimilar metals, like aluminum heads and cast iron blocks. The center layer is stainless steel and can be varied in thickness, which is how Cometic offers different compressed thicknesses like the 0.098 inches you get with this .030in gasket. This makes them a reliable option for both stock rebuilds and engines that see more demanding use.
