Show original supplier description

The BTR LS9 Head Gasket is engineered for performance and value, making it an excellent choice for budget power adder builds. This gasket is constructed from 7 layers of multi-layered steel, providing a robust seal capable of reliably handling over 1,000 horsepower. Key specifications include a 4.100-inch bore opening and a compressed thickness of .055 inches. These features are designed to work effectively with LS9 cylinder heads and are a direct replacement for GM part number 12622033. The gaskets are sold as a pair. While the product is generally versatile for LS engines, it's important to note that this specific gasket (BTR22033-2) is recommended for aftermarket cylinder heads, as it will NOT work with a Trick Flow Fast As Cast LS1 head. Always verify compatibility with your specific cylinder head and engine combination.
