Copper head gaskets are the superior choice for blown, nitrous, turbo-charged and high compression engines.
If a change in compression ratio is desired, a thicker or thinner gasket can be used. However, reason must be used when adjusting compression ratio with gasket thickness as every 0.25 mm change in thickness, nets approximately 2.5cm3
Copper head gaskets require the use of a sealant for oil and coolant passages (when applicable). Head gaskets on racing engines should be re-torqued after initial run- in, regardless of type (solid copper or composition). Factory torque specs and sequences are usually adequate. Allow the engine to cool for accurate readings. Always use a torque wrench and have it calibrated often. The copper head gaskets require clean, flat surfaces which are essential to seal a racing engine.
