OK, I heard from my buddy who has the racing head shop and he looked the heads over. His exact comment was that "they should be a hell of a gain over the stock castings I am currently running".

As the thread points out I got these from Frank, and he had them ported and larger vales installed and all that stuff before. So I asked the buddy with the head shop to look them over and see if the port job that was done needs any extra massaging or anything. He looked at them and asked if he did them, I said I didn't think so since Frank gave me another name. He then said the port work looks pretty good, and should be fine for what I'm looking for.

While he had them he:
Disassemble/clean/blast heads and parts,
Check springs, inspect heads,
Comp. Valve job and blend,
Resurface .005 and deburr,
set valve hts and backcut intake valves,
set spring pressures and assemble everything

And he said between the 5 angle valve job, blending, and back cutting of the intake valve he could pick up a more CFM, and with more CFM comes more power.

So with the extra .005, plus whatever had been taken off when Frank had the original work done, I think I might not go as thin on the gasket and look into a little more then the .015 I was originally looking at.
