Check other questions, and did not see an answer. Backstory: Driving around, discovered pin hole in radiator. Chose to drive home, since I was at my exit, and I lived right there. Blew head gasket. Fixes: Replaced radiator(Due to hole), Replaced water pump(found goo), and replaced head/gasket(It was cheaper).
I am doing a compression check, since coolant consumption problem seems to remain. Will I see any change in the results if my deck is warped? Or is the flat edge the only way to check a warped deck. Thanks for future answers.

Note to anyone else reading that might be wondering this: Engine has a block and a head, for the most part. The head seats on the head gasket, and the head gasket seats on the deck.

Yes, a warped lower end can affect the compression test. A seriously warped head of block can lead to compression leakage through the small space between the head gasket and the head or block. But I don't think you have a bend block, I suspect you used your old head with a new head gasket? You need to have a specialized company 'flatten' the head. I don't know the correct English term but it's basically making the bottom of the head completely smooth and level again.

I should have been clearer. I meant I replaced both the head and head gasket (head/gasket), but I hope it's nothing major. I'm ok with redoing the install, but don't want to pay for a short block. I'll do the compression test, and hope it holds up. – FossilizedCarlos Jun 5 '11 at 3:18
Did you use an OEM headgasket, or something aftermarket? Some of the inexpensive aftermarket ones don't necessarily work as well. Even some of the high-end ones can be problematic as they may require special procedures to get them to seal. If you went aftermarket, the solution might just be to get a fresh factory HG... – Brian Knoblauch Jul 30 '11 at 20:31
@ Brian I used factory HG, but aftermarket head and think they might just not match. – FossilizedCarlos Jul 31 '11 at 23:08
