Setup is L92 Heads milled .025 GM hot cam on a 6.0. what length pushrod do you think it would call for.Have the tool coming to check just looking for suggestions

 

I would guess a 7.375 depending on the lifters you are running with it. However, I would spend the $20 on the checker and measure and erase any doubt about it.

Running stock lifters.I had to order another pushrod tool the marks on mine were almost gone and hard to see.I know I need a shorter than stock pushrod because the stock lenghth pushrod opens the valve when I tighten down rocker with number 1 at TDC and exhaust valve partialy open.
