CHRYSLER DONOVAN 417 W/RING DO WELS 4.320 X .072 PRO COPPER H

The SCE Pro Copper Head Gaskets are designed for performance applications, featuring a 4.320-inch bore and a 0.072-inch compressed thickness. These gaskets are constructed from premium 99 percent pure copper sheets, precisely rolled and tested for flatness to ensure optimal cylinder head-to-block alignment.

Each gasket is annealed to ensure proper mating and provide improved cylinder sealing, evidenced by lower leak-down percentages. O-ringing of the block or heads is recommended for these gaskets. They are specifically designed to fit the 417 Donovan block and are intended for use with 11/16-inch ring dowels on 6-center bolt configurations. The product is sold individually.
