Those heads are rectangle ports, the iron heads you have are ovals. Bolting the rectangles on will hurt bottom end. Not really an upgrade in my opinion.
Sell them and get some edelbrock or brodix aluminum ovals.

If I changed the heads, the proper intake manifold would be installed as well.

The intake has nothing to do with what I'm talking about, the problem is that the ports on the old rectangle heads are too big, and smaller CI engines don't get any velocity at street RPM.
