Do I need a different Pushrod length?

I have the mods in my sig. The heads were milled .020" and I am running a .029" head gasket. I cannot for the life of me get the valvetrain to quiet down. I have stock lifters, and I am adjusting the rockers with the car running.

Can the noisy drivetrain be a symptom of an inccorect pushrod length? Car seems to run fine otherwise.

If you suspect the pushrod length, use this page as a guide to check the location of the rocker on valve stem.

If you find that you need 7.100" pushrods, I have a low mileage used set of Comp Cams pushrods. http://web.camaross.com/forums/showthread.php?t=361355
