Cool, loctite works, and even if it seeps a little, as long as it doesn't come out, will not see an psi change.

Really, .005 is nothing, think about gapping a plug from .030 to .035. I say just go to the next step, at least.

Now that I think about it, I actually would go 2 steps above standard on my builds, because I knew I was good to a 250 shot. That last engine went over 100k hard miles, and a bunch of N2O. I sold the short block to someone on this board, and they ran it like it was for probably another 100k. That was a 400, the strokers after that I know I went at least 1 step above standard, but would have to look it up to be sure exactly how much. I do have all the blueprint info on all my engines, so know I have that info.

You will not have any additional oil consumption or blow by over standard, if any, it would be so marginal you won't be able to measure it. Even at the widest gaps.

Ask Butler when you call, see what they say, but bet it will be kind of vague, since there's not a lot of negative impact in going bigger than intended purpose per the manufacturer's recommendations.
