The piston's, and ring's should have been measured first so that there wouldnt be a mistakes like this to occur, and each cyl. would have been matched to each ring/piston combo. Im guessing that you are using the feeler guage after the piston/ring's are intalled to check the clearance between the ring/cyl. wall. Also you have to take into account that the top section of the piston where the ring's are situated expand's when at OT so some of that gap will be closed some.
