Target compression ratio A/J

Zero deck huh? As your pistons are, cut the odd side .013" and the even side .022"

Now you have as deck heights.........

1) .001 2) .001

3) .000 4) .000

5) .002 6) .003

7) .002 6) .002

Then with an 84cc combustion chamber, 7cc valve reliefs, .039 8519PT1 head gasket, you have for compression ratios........

1) 10.13 2) 10.13

3) 10.15 4) 10.15

5) 10.11 6) 10.09

7) 10.11 8) 10.11

It's unlikely that the combustion chambers will all be 84cc but, still, close enough.
