Default LS7 MLS head gaskets

With all these large bore engine blocks going around (warhawk, GMPP-LSX, C5R, ERL)

Does anybody have information LS7 MLS gaskets? bore size, thickness. Hypothetically they could even be used on 402/408 setup(?)

For large bore engines your options are limited to cometic and Fel Pro MLS (havn't used them yet, so i'd rather not expirament).
