Eddy heads and what else !!

First of all, why are you pulling the heads? Their just going to put heli coils in your aluminumm heads, that can be done with them installed!
My next question is why not have the heads checked for flatness if you must remove them, dont just automaticly have them resurfaced, you start cutting you heads you may have to have the intake cut as well, it snow balls.
At bare minimum if you remove the heads, replace the valve seals.
My 2 cents
Good luck
