The old rings were gapped for nitrous use (but not used), top ring gap was over .030". This owner will not use nitrous, that was one of the reasons for me fixing the engine.

4.600 bore engine I would have top ring gap over .030 for N/A and a little more if forced induction or nitrous. A little extra gap doesn't hurt anything, not enough could get ugly fast. Dan
