The Texas Speed LS2 / L92 / LS3 / L99 MLS Cylinder Head Gasket is a GM-style multi-layer steel head gasket for the 6.0L and 6.2L Gen IV LS engines. Texas Speed lists it for the LS2 and L92 and states it also works for LS3 engines, with the L99 named in the title. The gasket is .051" thick with stainless steel faces, which Texas Speed recommends for stock and mildly modified engines. It is sold individually, so two are needed per engine.
This is the 6.0L/6.2L MLS head gasket choice offered inside the Texas Speed heads and camshaft gasket kits and engine rebuild kit, and it can be bought here on its own for a head gasket replacement, cylinder head swap or camshaft upgrade. Order one gasket per cylinder head. The supercharged LS9 and LSA use a different Texas Speed gasket, TSP-HG2033, with a 4.10" bore and .054" thickness.

FAQ
What engines does the Texas Speed TSP-HG0046 head gasket fit?
Texas Speed lists it for the LS2 and L92 and states it also works on LS3 engines, with the L99 included in the product title. These are the 6.0L and 6.2L Gen IV LS engines found in the 2005 and newer vehicles shown in the list.
Is this a single head gasket or a pair?
It is a single gasket. Texas Speed sells TSP-HG0046 individually, so order two to cover both cylinder heads on one LS2, L92, LS3 or L99 engine.
What thickness is the Texas Speed LS3 head gasket?
Texas Speed lists this GM-style multi-layer steel gasket at .051" thickness with stainless steel faces, recommended for stock and mildly modified engines.
Which Texas Speed gasket do I need for an LSA or LS9 instead?
The supercharged 6.2L LS9 and LSA use the Texas Speed TSP-HG2033 MLS head gasket, which has a 4.10" bore and .054" compressed thickness and is also sold individually.
Will this gasket fit a 5.3L or LS1 engine?
No. The 4.8L, 5.3L, LS1 and LS6 have a smaller 3.910" bore and use the Texas Speed TSP-HG8544-PAIR or TSP-HG9226 head gaskets. This gasket is for the larger-bore LS2, L92, LS3 and L99.
