Just noticed: Lovin the big chunk of alloy above and right of the head in the top photo, only just noticed it. Looked through the box and found an even bigger one. This alone totally backs up Brent's advice as far as I'm concerned, these cant be ready to go out of the box heads.
I also found the second head had 2 exhaust ports that are way of square on one side and would probably cause overlap to the exhaust headers. There was also damage to the edge of the faces on both heads shown in the little circles below and another nice big chunk of alloy floating around from the milling. This one was laying around in the top near the valve springs, circled in first photo too.
Here's a closeup of the odd port shape, note the bulge on the left side and lovely die grinder work!
Cheers,
Andy
