I have shifted at 6k with stock valvetrain with no problems at all. I would not go any higher if you have your stock cam.

There is probably no reason to go any higher than 6k w/ the stock cam. I think peak is around 5400 if I'm not mistaken. 5700 seems to work best on the 1-2 for me.

6k seems a bit high because it wont really pull that hard all the way up there with the stock cam i say put it at about 5800 unless you have a cam to finish out the top end

I have my shifting at 5500. I am spraying a 125 shot. Do you'll think I should raise it any more and would i benefit from it at all ?
