Hi Rick,

The thickest SBC head gaskets we offer are 1144-071. They are .071" thick with a bore size of 4.200":

They are MLS head gaskets, so the sealing surfaces of the heads and need to be compatible with MLS head gaskets (surface finish of 60 Ra or smoother).

If you cannot use MLS head gaskets, the thickest composite gaskets we are 1044. They are .051" thick with a bore size of 4.200":

These are both obviously thinner than you're looking for. You may end up needing to look at other head gaskets or changing components.
