Upgrade your engine's performance with the Cometic GM LS1 SB 3.910 inch Bore.066 inch MLS-5 Headgasket. This multi-layer steel (MLS) head gasket is designed to provide maximum sealing performance for high-output engines, with no sealants required.

- Compressed operating thickness of 0.066 inches
- Ideal for high-output engines with aluminum or cast iron blocks
