Performance composite gaskets are the most versatile for turbo charged engines. These gaskets incorporate specific fire sealing methods for all conditions and head or block materials. Steel wire ring gaskets are best for street/strip/race IRON head applications. Copper wire ring gaskets are best for street/strip/race ALUMINUM head and/or ALUMINUM block applications. We recommend the Copper wire gasket for most TA V3800 block applications. Loc wire gaskets offer an even better seal but will require special machining of the cylinder head to incorperate a receiver groove.
