* Measuring Deck Height: The Deck Height measurement is from the top of the block or cylinder down to the top of the piston, if the piston sticks up above the top of the block or cylinder, the deck height will be negative ( -.010") Remember to figure in the thickness of your headgasket (if you have one) into your deck height. (if your deck is -.020, and your head gasket is .100" thick then your deck would be .100 + (-.020) = .080) If your deck is -.100 and your head gasket is .050" thick, I think you may have a problem. .050 + (-.100) = -.050
