This is JUST the head gasket and NOT the studs too. You can choose form the drop down between;
1) Stock size (11mm) head studs AND no machining is required to your block. The gasket holds the rings in place rather than a groove in the top of the block. Although it compromises ultimate sealing capacity (in comparison) its still THE best solution for 2019 onwards. We now use this option INSTEAD of the wire ring head and special gasket on all our retro fit head gasket upgrade jobs.
2) The machining type gasket which needs a groove to be machined in your block and we advise using the larger 12.7mm L19 head studs also. This is the Ultimate sealing solution for your cast 4G63/4G64 block.
