apparently you do want a "snug" fit to know the accurate size of the gap. I always used a "smooth" feel. I can drop the feeler gauge in, it doens't wiggle side to side at all, and I can slide it up and down against the cylinder wall, through the gap, and it "glides" through.

when I talked to the tech guy at KB, he told me that my gaps would actually be a bit bigger than what I was measuring because of how I was measuring.

oh well. too big on ring gaps are better than too small. Plus, I think I've seen some write ups from different builders online who say that they've noticed no loss in Hp with as much as a .060" ring gap
