Setting industry standards, SCE Pro Copper head gaskets are recommended for serious racing engines and are used to seal metal-shredding Top Fuel, Top Alcohol, and Pro Mod nitrous-powered monsters.
Created from solid copper sheets rolled to SCE specs, these Pro Copper gaskets are inspected for flatness for uniform contact on your sealing surface.
They are then processed and heat-treated to ensure conformity to your mating surface for measurable gains in cylinder sealing. Yes, there are cheaper head gaskets, but inferior material and uneven load distribution could "torch" your savings--not good!
To attain a better fit, better leakdowns, and better ETs from your monster horsepower, seal it tight with SCE Pro Copper head gaskets.
