Oops, just found this very useful post.


Still have original question however, ideas on how to determine any given piston is at top of travel,,,,making no difference if on compression or exhaust stroke,,,just by observing lifter positions in their bores.

hi, run # 1 piston to tdc. you can remove springs on # 1 and # 6 same time . with out air pressure or rope. after installing said springs, rotate to # 8 , it and #5 are at tdc, change them both. the valves will drop down some onto piston tops. I change my springs, this way. #1& #6, # 8&#5, #4&#7, #3&#2. follow the firing order. can't miss. there is always two pistons at top same time. one is on firing tdc, other is on overlap.
