Engine Cylinder Head - PCE281.1082

These Speedmaster MLS head gaskets feature 100% stainless steel construction. We don't use inferior mild steel like some other aftermarket gasket suppliers. To aid in sealing, both outer layers of our MLS gaskets are covered with a high temperature coating. You won't find better value in head gaskets for a LS anywhere. INTAKE / EXHAUST GASKETSUnlike most other Chevy V-8's, the LS-series engines utilize individual O-rings around each port to seal the intake manifold to cylinder head. The LS1 / LS2 / LS6 style heads & manifolds use GM pn# 12533587 and the LS3 / L76 / L92 style heads use GM pn# 1290125. On the Exhaust side of the head, all non-LS7 heads utilize the same MLS header gasket. The part number of the exhaust gasket is GM pn# 12901125.Speedmaster is currently working on a line of MLS exhaust / header gaskets. Check with your salesman to see if we have a MLS exhaust gasket available for your application.
