Show original supplier description
The Brian Tooley Racing head gasket set is engineered for Gen III/Gen IV LS engines, including 4.8L, 5.3L, and LS1 applications. It features a precise 3.910" bore opening and a compressed thickness of .051", ensuring a reliable seal. This gasket set is sold as a pair, providing a complete solution for one engine. The 4-bolt design is compatible with a range of LS engine configurations. Brian Tooley Racing explicitly states that these gaskets WILL NOT work with early style notched LS1 cylinder heads. Please ensure your cylinder heads do not have this feature before purchasing. As per its EMS Code 4 designation, this product does not require an Executive Order in California and is legal for sale and use in all 50 states. Replacement parts are included with the gasket set.
