center port intake manifold 1957 ford retractable 312
the center port gets so hot it burns the paint off --it reachs 275 degrees is that safe--I wired the buterfly open on the exhaust that help a little any sujestion and is that normal to get that hot.

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.
