Cometic Ford 289/302/351 4.030 inch Bore .027 inch MLS Head Gasket (Non SVO)

This Cometic Multi-Layer Steel (MLS) head gasket is built with a 4.030 inch bore and a compressed thickness of .027 inches. It's designed to handle the demands of high-output Ford Windsor V8 engines, fitting a wide range of vehicles like the Ford Bronco, Econoline vans, and even classic AC Cobras. Because it's an MLS gasket, it offers superior sealing performance without needing any additional sealants, making installation more straightforward.

The gasket's construction features multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This advanced design helps prevent leaks and ensures a solid seal, even when mating aluminum heads to cast iron blocks, as it can manage the shearing forces that occur between different metals. The center layer is stainless steel, allowing for precise thickness control.
