500hp Vs 500efi Heads

Is there any difference in the heads between a carbed HP500 and the 500Efi? I dropped an exhaust valve in one of my efis and need a set of heads for it, but wasn't sure if they were interchangeable? thanks

Would they be the same castings as used for a 502 EFI ?? I have 2 motors I am rebuilding and I am considering going to aluminum heads. I would be willing to sell them if so.

What do you mean 502 EFI?

502 MPI?
500EFI?

Sorry for the confusion--- 502 Magnum MPI

I work in the automotive field and all fuel injection is referred to as EFI. Sorry!!!

The HP's have larger valves than the MPI's do. The HP's have .230 intake valves I think.
