I'm trying to finish up a 511/400 stroker motor and have a head gasket question. After measuring the piston to head clearance and figuring in the piston rock, I'm not sure how comfortable I am with using the .043 thick head gaskets I have. I'm thinking of trying the Felpro 1105 where they have a .051 thickness. Can I use that gasket on a 4.375" bore where it has bore size of 4.59"? Thanks.
