It pays to measure the ring end gap with any new set of rings.
Use plenty of oil to soak the new rings, and smear the new cyclinder with oil to.
Then fit new ring, one at a time inside cylinder, (without piston, but AS If it was on piston, and close up the ring carfully not to scratch the bore, to bring the 2 ends together. There is supposed to be a gap, the ends are not suppose to meet. If they do meet, then file bit by bit off the end of the rings.
I would say check with the old cylinder first, practice a bit to avoid scratching the new bore. Or test for end gap with the new rings on the old cylinder first.
If there is no end gap when the new rings are set in the new cyclinder, how would one expect the rings to close up when fitting the new piston etc ?
Snap !
Pays to check at least. can't remember off the top what the tolerances were, but I think about .003 or .005 inch, but I'm guessing.
Someone else here might know what the piston ring end gap tolerance is for a HT ?
Some discussion here about the same thing in principle on VW
