SBChevy Head Gasket is oil soaked

A rebuilt 350 with mixed head castings, supposedly test run for 30mins. I remove one head, all is dry. I remove the other head only to find engine oil on both sides of the head gasket.

The gaskets look really cheap. The torque on both heads seemed the same, but it didn't quite feel like 70ft-lbs to me (hard to say). I'm getting rebuilt 441 heads and have fel-pro 1003 (.041 compressed) gaskets.

Is there a tool or a way I can check to see if the block was machined straight (or the suspect head)? Really concerned as this looks like a disaster waiting to happen, and quickly. I don't have access to a machine shop.

The tool most all machine shops use is a certified straight piece of steel stock about the length of a yardstick and approx twice as thick and deep, with this you can measure with a feeler gauge or a dial vernier or indicator, and find out if it is warped, measure lengthways in three places ,then diagonally, then up and down. Anything over .0025 is suspect, anything over .004 in 20 inches is not acceptable.

Real common to find wavey block decks that cause this... Most that have been a little warm tend to have this problem and of course decking the block is a good cure... Also most stock combinations will allow plenty to be removed... 0 decking is common in race engines for optimal compression combined with certain head gaskets...
