Thanks for your personal view and honesty Mark.
I plan to weight the individual parts to see if there is a big difference first as there was some damage on a couple of pistons (pitting etc).
my father who is also an experienced mechanic and has rebuild many engines highly recommended this and can be better than spending money on fancy cams and valves.
If there is significant difference in weight I will re balance them. IMHO the forces that are created from the moving pistons can make a significant difference on bearings, smoothness, and horse power. I agree about the flywheel and crank but this is something I can't do at the moment.
I'll let you know on Sat the weights of the pieces.
Would these marked areas on the rod piece be ok to round off to remove a few grams?
And what about the pistons? Where inside can I remove material? I know some pistons have special areas made to remove material because factory specs are very rough and not precise.
