3 Reasons For Choosing A Copper Head Gasket
Author: SCE Gaskets
- Extreme performance enhancing modifications; 15:1 or higher compression ratios, high levels of boost, or nitrous kits exceeding 200 hp.
- Piston head clearance adjustments. If for example, @TDC, the piston and rod assembly is too close to the head, a thicker head gasket can restore the proper clearances. SCE copper head gaskets are available as thick as .093".
- Compression ratio adjustments can be made by using thicker or thinner gaskets. However, reason must be used when adjusting compression ratios with gasket thickness, as every .010" change in thickness will net a change in volume of about 2.5cc. This method will never raise an 8.5:1 street engine to a 12.5:1 race engine, but small adjustments are possible.
