i was thinking the same thing. or whatever ho the heads were off of are warped some how did you ever get them checked/milled down. happens alot. or worse case the block has a warp ? oh just to be safe. you did use NEW head bolts to tighten the heads down didnt you. if not some nice ARP's would solve the problem. and while you have the heads off check them for trueness.
