What about ring gap on a long rod motor?? A guy around here preaches no ZGS rings on long rod motors....any logic to that???
The longer the rod the better till the point of being in the oil ring is good.

On the zero gap rings, seems as if that's not nearly as good idea as once thought. When I ordered my Ross pistons, I was advised to stay away from them and go with file fit. Here's something I found on Federal Mogul's web:
