nor cal i inspected heads as well as engines for many years at GM.if you take a .010" shim on each end of h ead and use a feeler gauge as long as you are within .003" you should be ok.if you get a .009' feeler in that would be +.001" if you get a .011' feeler in that would be-.001" and so on. measure it on both edges and in center then do it accross like from inside to outside. It should take you about 30 minutes to do both heads.

-You don't use anything on the headgasket for additional sealant-Bring it to a machine have them checked out the head if you're not sure about your work-

yeah the head gasket blew from overheating. However I just came across another problem that's going to require new heads. when i took out one of the rocker arm bolts i noticed metallic stuff in the threads of the bolt. I thought maybe it was thread sealant of some type and forgot about it. Now as I started reinstalling the rocker arms, the bolt would even begin to tighten. Come to find out.... It was the threads themselves from the head. So.... Where do I find the best price on new heads for this car. Do I go to a pick 'n pull? This is turning into a nightmare.

look around your local area for heads for best price. you can always usea heli col if the rocker doesn't require to much torque.
