Guess that depends on your setup. I have milled heads and am using 7.325s with preload of .055"-.070". It's not noisey, but I've been wondering if .070"-.095" would be better, and quieter yet.

I swear if we put all these threads together, compiled all the info in a spreadsheet type program, no one on earth would ever have to measure for pushrods again. You could simply "consult the pushrod suggested length chart"

QFT... I KNOW there is a length checker out there that is easier to use on an LS* but I haven't seen it in a while. The normal ones are a bit of a pain because you can't really get your fingers in there.
