Cometic LSA & LS9 4.100 x 0.075 MLS-5 Multi-Layer Head Gasket

Product Details

---

Lingenfelter offers these 0.075" thick multi-layer steel or MLS head gaskets that are the same bore size as a stock LSA or LS9 head gasket but are thicker so they reduce compression by roughly 0.4 to 8.7 vs stock 9.1.

Like the OEM LSA/LS9 head gasket, these gaskets are compatible with the factory LSA/LS3 style head bolts or the larger LS9 head bolts.

This gasket can also be used on the 6.2L & 6.0L LS3, L99, LY6, L96 and other similar applications to reduce the compression ratio on those engines. This is useful for boosted applications or lower octane applications.
