Since it's quiet around here, I thought I'd add another interesting factoid from the rebuild.
My rods stretch just about 0.6mm, revving to 7.5k rpm.
I know this because:
1) piston 3 had a carbon free area in a shape that matched the squish area of the head. The other pistons didn't.
AND
2) I use a gasket 0.8 mm thick
AND
3) piston 3 was 0.22mm up above deck height and all the others were 0.20mm or less up.
So there we go. And we shaved 0.04mm off piston 3 so that now it's all back together, all the pistons are below 0.20mm up.
