Description

OLDSMOBILE V8 4.200 X .080 PRO COPPER HD GSKT

MIA's Description

The SCE Pro Copper Head Gaskets are designed for Oldsmobile 350-455 engines. These gaskets feature a 4.200 in. bore and a 0.080 in. thickness. They are constructed from premium 99 percent pure copper sheets, precisely rolled and tested for uniform flatness to ensure accurate cylinder head-to-block alignment and prevent uneven loading.

Each gasket is annealed for optimal mating and improved cylinder sealing, resulting in lower leak-down percentages. O-ringing of the block or heads is required for installation. These Pro Copper gaskets are available in various bore and thickness combinations to meet performance needs.
