ZR1 Head Gaskets for Boost
New ZR1 GM Head Gaskets for LS2 engine? Can anyone think of a reason not to use these - since they were after all designed by GM for boost.

ZR1 info...
The engine block is constucted of cast aluminum and has the six-bolt main bearing caps common to all LS-x series engines. Additionally, the block has enlarged vent windows between the second and third bulkheads for better bay to bay breathing. During the finish bore honing process, a deck plate is installed to simulate the block distortions when the cylinder heads are secured. The use of the deck plate ensures a higher degree of accuracy and promotes piston ring fit and cylinder head sealing. Sealing the cylinder heads to the block is a stronger four layer head gasket
If the standard 5 layer was sufficient why would GM develop a new gasket, it just seems that this one should be better, or GM would just release a modified bore version of the 5 layer. Just a thought...
