For $3500 do you think i should go with that or a speed inc or Texas speed motor?
*edit: I didn't get those rings tho, I got the rings that came with the Mahle pistons...

With 6.0L heads and MLS gaskets, that puts the compression at about 9.45:1...
Are you sure about that CR? I built the same set up -4cc mahle & AFR 72cc heads with mls gaskets. I figured it was ~9.1 to 1 but I'm not sure I figured it correctly

do all the math for that, and SCR is 9.446, CID is 346.677, or 5.681 liters

I think I just figured out the difference in the 2. The link you posted uses a positive value for deck height. PianoProdigy's spreadsheet uses a negative value. There was a big debate about this, but it ended up being that the negative number is correct. So I wouldn't trust that link...
