I used a .140” thick Cometic head gasket with a 4.5 stroker to use a longer rod in a short deck platform with a 4.5” crank and 6.7” rods. The pistons were above the deck .1” or more. With the right piston it would be close using a 7” rod and 4.5” crank in a Pontiac doing something similar. 6.86” ish for the 4.75”. I took the Cometics apart and stacked them to get the height I wanted. The height I end up with was available from Cometic. I suppose you could stack the Cometic's and go taller yet. I was running out of room on the top rings, there was a little more room though. lol
