I am doing a head change from peanuts to large oval, on a standard bore, standard deck 454, flat top, piston, .018-.020 in the hole. I already have a set of head gaskets, Fel-pro 1017-1, composite, steel core.
Is this gasket ok to use, or should I be using some thing else, like the 1037?
my main concern I guess is the bore size and the core material. The 1017-1 has a 4.54" bore with a steel core and the 1037 has a smaller 4.37" bore with a stainless steel core.
The 4.54" bore just seems a bit large for a 4.25" cylinder bore size? Would there really be much of a compression difference between the two, to justify buying a new gasket?
