Cometic MLS head gasket for GM L18 Vortec 8100 Gen-VII big block V8 (.036" compressed thickness) with 4.450" bore (right side) features embossed stainless steel layers with Viton coating for robust sealing performance. The multilayer construction is suited for aluminum-to-aluminum or aluminum-to-iron applications and resists corrosion.
