PONTIAC V8 4.380 X .093 NO WAT ER PRO COPPER HD GSKT

The SCE Pro Copper Head Gaskets are designed for Pontiac V8 engines. These gaskets are made from premium 99 percent pure copper sheets, precisely rolled and tested for uniform flatness to ensure accurate cylinder head-to-block alignment. After processing, they are annealed to achieve optimal mating and improved cylinder sealing, evidenced by lower leak-down percentages. The P283893 features a 4.380 in. bore and a compressed thickness of 0.093 in. O-ringing is recommended, and machining of the block or cylinder heads may be required for o-ring installation. These gaskets are sold individually.
