Oversize stems are necked down to standard at the keeper area. No special consideration is needed for keeper or retainer fit.

Agree with eliminating the problem when I run into it. No sense in passing along a headache to the next guy who happens to work on it.

Way back years ago, before I knew better, I had my virgin big valve -461 real fuelie heads knurled.

Wished I hadn't done it.

I took them in to get a valve job done and told the guy that they were fuelie heads and you know the look that I got from him, "Like sure"!

Went to pick them up and he said, "Right, they are real fuelie heads!"... Take good care of them because I have never seen a real pair before...
