Nope. Wrong heads IMO. They will ned a bit of work to reach your proposed goal. Plus a race convertor. Then you have the cage, fuel system, new belts, SFI dampner, SFI flexplate, aftermarket axles... The Ross pistons will fit loose in the bores... they are supposed to be fairly tight. Did you have the block sonic tested BTW? If not, do that before you do anything else. I think overall, you have anotehr $6-7K to spend unless you are really hooked up and doing it all yourself. Still by the way, dirt cheap for what you'll end up with.
