SCE Pro Copper Head Gaskets

4.0 out of 5 stars 19 Customer Reviews

Not all solid copper gaskets are created equal. SCE uses premium 99 percent pure copper sheets that are precisely rolled to our specifications and tested for uniform flatness to assure precise cylinder head-to-block alignment and eliminate uneven loading. After processing, each gasket is annealed to ensure optimum mating and provide measurable gains in cylinder sealing, as evidenced by lower leak-down percentages. O-ringing is recommended. Pro Copper gaskets are available in many bore and thickness combinations to suit your performance needs.
