Thought it was kind of weird how the number one cylinder had that clean half crescent on it? Almost like maybe a water leak or something....
Of course I did look at the cylinders and all four corners and just with a feeler gauge of course I couldn't get more than .010 above deck.. I'm sure I could get away with the Edelbrock/fel pro .050 gasket, but since I got the cometic I'm going to go with the .070 and the quality...

So r u gonna pull it apart and have the decks machined for the Cometics? The decks need to be much smoother. U just can’t randomly install them and hope they seal. Kim
