The Texas Speed 6.2L LS9 / LSA MLS Cylinder Head Gasket is a multi-layer steel head gasket for the 6.2L LS9 and LSA engines. It has a 4.10" bore and a .054" compressed thickness, with stainless steel faces that Texas Speed recommends for stock and mildly modified engines. The gasket is sold individually, so two are required to reseal both cylinder heads on one engine.
Texas Speed carries this gasket under reference 25-TSPHG2033, and it is the LS9/LSA head gasket choice offered inside the Texas Speed heads and camshaft gasket kits and engine rebuild kit. It suits a head gasket replacement, cylinder head swap or camshaft upgrade on an LS9 or LSA. Note that the 4.10" bore and .054" thickness differ from the LS3 gasket (TSP-HG0046), so match the gasket to the engine before ordering.

FAQ
What engines does the Texas Speed TSP-HG2033 head gasket fit?
Texas Speed lists it for the 6.2L LS9 and LSA engines. Those are the supercharged 6.2L engines used in the Corvette ZR1, Cadillac CTS-V and Camaro ZL1 applications shown in the vehicle list.
Is this head gasket sold as a pair?
No. Texas Speed sells TSP-HG2033 individually, so order two gaskets to cover both cylinder heads on one LS9 or LSA engine.
What are the bore and thickness of the LS9/LSA head gasket?
The gasket has a 4.10" bore and a .054" compressed thickness, which Texas Speed lists as the available thickness for the LS9 and LSA.
Can I use this gasket on an LS3 or L92?
Texas Speed lists this gasket for the LS9 and LSA only. For LS2, L92, LS3 and L99 engines, Texas Speed offers the TSP-HG0046 head gasket at .051" thickness, also sold individually.
Is this gasket recommended for high-boost builds?
Texas Speed recommends its stainless-faced MLS gaskets for stock and mildly modified engines. Confirm the gasket choice with Texas Speed or Berry Performance Sales for heavily modified or high-boost LS9 and LSA builds.
