Product Description
The BILT 2 PERFORM 1997–2003 GM LS1/LS6 Engine Head Gasket and Head Bolt Kit combines the critical sealing and fastening components needed for cylinder head installation on compatible Gen III LS engines. Designed for 1997–2003 LS1 and LS6 applications, this package includes a pair of 3.910-inch bore cylinder head gaskets along with a complete Pro Series cylinder head hex bolt kit.
The matched head gaskets provide sealing between the cylinder heads and engine block, while the included Pro Series hex head bolts provide the required cylinder head fastening hardware. Combining both components into one package eliminates the need to source the head gaskets and cylinder head bolts separately.
Ideal for LS1 and LS6 engine rebuilds, cylinder head replacement, performance builds, and engine refreshes, this kit provides a convenient solution for servicing the cylinder heads on compatible GM Gen III LS-series V8 engines.
