Before going too deep into the engine, check the intake gaskets. There has been many discussions on the failure of Fel-pro intake gaskets. Particulary the 1247 gasket set. The gaskets break down quickly for some reason. I have a pair of new 1247 gaskets hanging on a nail in my garage. So far, they haven't leaked. I doubt if they will as long as I let them hang on that nail. Instead I used Edelbrock intake gaskets, since I have Edelbrock heads and intake manifold. As far as head gaskets, most builders recommend Fel-pro 1020 head gaskets.
Standard bore on a 428 is 4.130. indicating your bore is only oversized by .002. If it has been bored .030, your bore would be 4.160.
