Machining has come a long way since then. I also find that hard to believe, as I've managed to get flat surfaces using this measuring method and using equipment that's been around since long before the eighties...

Not a good idea IMO, but I see what you're saying... Measure your head! make sure they got it flat

Yes... I was going to mention pressure testing, but forgot... That should reveal any major cracks... Dye testing can be done to reveal fine cracks that enlarge when he head gets hot, but pressure testing is enough 99% of the time.

Didn't you say that the block is warped?... that's very common on V8's and severely overheated engines... I would expect that that is your problem. If you measure .002 or more on the block, and the head is flat, then I would send the block to get it decked while they pressure test your head

BTW on this last head, the resurface I payed for is amazing... I've never seen anything like it. $35 and it looks like it was done by a laser beam. I can faintly see the tool marks if I look closely in the reflection
