5:45 am weighted piston + rings + wrist pin: Cyl #1 518.0 gr Cyl#2 517.6 gr Cyl#3 518.8 gr Cyl#4 518.8 gr Deck height on all cylinders +/- 0.001" of 0.0. No additional shims. A 7.0 : 1 compression ratio Page 22 indicates a shim stack of 0.17. With shims from kit plus additional 0.01" shim stack is 2 x 0.06 + 0.04 + 0.01. Will re-evaluate after measurement of combusion chamber volume and re-calculate compression ratio.
