Cometic Ford 429/460CI Stock Block 4.50in Bore .040 thick MLS Head Gasket

This is a Cometic Multi-Layer Steel (MLS) head gasket designed for Ford 429 and 460 cubic inch engines with a stock block. It has a 4.50 inch bore and a compressed thickness of 0.040 inches. This gasket is built to handle the demands of higher output engines and fits a wide range of Ford and Lincoln vehicles from the late 60s through the mid-90s, including models like the Ford F-250 and Lincoln Continental.

Cometic's MLS gaskets are constructed from multiple layers of stainless steel, which gives them increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can withstand temperatures up to 482 degrees Fahrenheit, ensuring a strong seal even in harsh conditions. These gaskets are suitable for use with aluminum heads on both aluminum and cast iron blocks, as they can manage the shearing forces that can occur between different metals. Because they are designed for maximum sealing performance, they typically do not require any additional sealants.
