Could the rings have been broke upon installation?

I would run only moly file fit rings. For gas the top ring end gap should be 22-24" and the second ring end gap 12-14" and the oil rail rings 0.030"

I'd follow the ring mfg instructions on ring for your application I run .020 top .022 2nd yea .022 .speed pro says to run .022-.024 on 2nd ring for oval track .They want a gap to release pressure between the 1st and 2nd rings so the compression ring doesn't flutter.the 1st ring is for compression the 2nd is a s****er.I also run srp forged pistons, gap is alot different for hyputectic pistons

The rings were either butting together from lack of end gap, or you had detonation in those 3 holes. Look at the ends of the rings that are broken and see if they are shiny. If they are shiny then they were butting, if not then it could have been detonation.

Follow dirtracer7's advise for gapping your next set of ring's. He is 100% correct on his advise.
