I checked the heads with a machinist's straight edge not even two months ago before I put this setup together. They weren't perfect but within .003"-.004" if I remember correctly. I've already called the machine shop and talked to them, I'll pull the other head this afternoon and double-check how flat they are before any final decision. But as of now I'm looking at heads milled, gaskets, probably new head bolts/studs, check the block deck. They're magnum heads and if I remember correctly from the last time I looked, ARP doesn't offer a head stud kit but they do have bolts.
