But, like anything else, there's a "contrary view" as to the importance of getting your valve gaps "just perfect." In fact, here's a pretty good tidbit on valve gaps really not mattering as much as you think they would, and specifically addressing the ol' P&G Valve Gapper: http://www.dragracingonline.com/tech...sion/ii_4.html

But since it sounds like you need to re-tighten the nut anyway, it's not going to be perfect and you'd need to check it with a feeler gauge anyway - or does the Gapper tool both turn the adjusting screw and then hold it in the exact position while tightening the nut? I had to re-do the adjustment 2-3 times per valve until I figured out how "loose" it should be before I tightened the nut which would close the gap just that touch more to make it perfect.
