Bought the set, one piston broke.

I am running a fairly low compression, n/a motor and #4 piston broke above the top ring land.. No extreme engine conditions, ring gap is verified as being on the looser side of the gap tolerance, no burrs on the rings from gapping. Motor was running 13.6-14.9 afr. And all valves have over .23" of clearance.
