If you have to cut the block deck to square it up you'll have a positive deck height. I hope your going to run a vacuum pump with those rings.

The deck hieght is -.009 on one number 1 and right at +.003 on number 6 That was doing a quick check to see what it ended up at, I will check all 8 tomorrow I wasn't planning on running a vacume pump on this motor due to being told that these rings are the stock ring sizes used in the new car motors like the LS1, 3rd. gen Hemi and the modular Ford V8 Diamond furnished the rings with the pistons, I told the rep I work with that I wanted a standard tension oil ring, not a low tension oil ring The oil rings are tiny and they don't seem to have a lot of tension when moving them around in the piston ringlands with my fingers I guess I'll see BTW, are you or have you used this size rings in a motor and if so what where your results?
