I would like to shoot for 10:1 unless people have strong opinions otherwise.

 

If I am doing the math correctly which I believe I am.

With an LQ4 8cc dish piston, a 60cc head, .89 gasket you would be around 9.8:1

Every Block and piston is different. I have only measured a few but I Found the piston to be around .005 - .008 out of the hole. I believe the dish is 8cc and the math seems to check out with a stock Gasket thickness.
