Yes it normal for it to get that hot, you can block off the cross over on the intake manifold to prevent that from happening.
I Googled it and there are several ways you can do it, I have both a 57 Thunderbird & Skyliner that have burned off paint & if ever get around to repainting the blocks that is what I'm going to do.
Gaskets are sold with a smaller hole or you can put a piece of thin sheet stainless steel between the gaskets and the heads to block the heat off.
