Ring Gap Question, How much is too much?

I would say that it is too much at .27 unless you are running a big shot of NOS, in which case a larger gap is better. The mopar books say somewhere around .10 to .12 for top and second rings, I believe, if my memory is correct. I had around .24 and had too much blow-by. Can you get an oversize ring and file fit them. That would be best if you are not boring it out.
