CONFUSED!?!?!?!?!

Ring gap provides a space for the ring to expand Circumferentially and still not touch end to end (which would sieze the engine). Ring gap should be measured in an unworn location in the bore. If looked at in a location that is worn, it is not accurate. Unworn locations can be found at the bottom of the cyl. Usually 1/2" up from the very bottom. Another location is above the top ring/ridge. (if and only if this area has never been ridgereamed or honed in some abnormal way).
In all cases the tightest gap measured on a ring in various locations in a bore, can be assumed to be the tightest spot in the bore)
One way to approximate bore taper/wear is to measure ring gap in the most worn spots (just below the top (1/16") of the ring wear area), and at the bottom as noted above. The change in Circumference converted into diameter will indicate taper in the bore (not as accurately as a set of cylinder micrometers used correctly, but good enough to determine if a cylinder is worn drastically.
All single piece oil control rings are old technology and should (in almost all cases be replaced with three piece rings with (effectively) no gap. Cleaning the ring groove is drastically important, as is doing it without removing metal. The groove clearance (side of ring to ring groove) is important because if too large it causes a pumping effect of oil around the back side of the ring. RIng groove taper (wallowing out of the squareness of the groove) is also a reason to junk the piston. Or if it is irreplacable, the groove can be cut wider and a steel repair ring can be inserted (they look like a scraper rail from a three piece oil ring) to take the piston back to usable. I hope this helps, good luck, JimN

top compression ring width 1/8 oil ring width 1/4 top comp. ring side clearance 0.004 other ring side clearance 0.002-0.0035 sleeve taper 0.0155
top ring side clearance in groove 0.006

I have not had my H apart , but my super A had cast pistons with 4 grooves. top is compression other 3 were oil rings if i remember right.

if the other reply is hard to read it wasn't typed the way it posted.
