Hi Tom, Thanks.
What I'm trying to get to the bottom of is what you are trying to match when putting a set together.
Match deck height - 5 or 6 on the cylinder. I get that bit.(lining up heads and CR)
What about cylinder/piston size groups 0,1,2,3 - is it necessary to match that as well?
Then there is the group weight. The 930 manual says you can be out by 8 gms with an individual piston, but groups are +/- 2gm. So, do you match size groups and live with 8gm variances or ignore size groups and try and balance pistons?
I have a chance to buy 5 new P/Cs for a 930 and trying to work out where to go from there given 5 is not a particularly useful number.
Interestingly your chart quotes 930 CR as 7.5
Regards
Alan
