After removing the heads cyl7 head port was caked in carbon/oil build up and top of piston was blackened. All other were fine.

LS3 factory rev limit is 6600

valve can develop a leak if overheated also.

So there was no issue with the piston or rings. That's just what the shop assumed. When they sent the heads to he checked they found the bent exhaust valves. That being said since I'm getting a stroker short block my stock one is for sale. Let me know if anyone is interested.
