Yes, that is way too high a compression unless your planning to run high octane racing gas or additives. It is around 11:1, and i'm guessing from your comments you are wanting something more in the 8-1/2-9:1 compression range. The stock 292 pistons have around a 27cc dish in them and with a 72cc head this will put you right in the compression range you want. As for the pistons sticking above the deck surface, I would trim them to make them all consistent at zero deck height.
I would also run the 1.6 on the exhaust. I would also check the pistons ( from skirt to top ) and make sure they are the same and If so I'd be taking a close look at the Crank. Because I wouldn't think they would be that Much difference on the pistons Above the deck.
God doesn't like ugly.
