What length pushrods for unmilled 5.3 heads??? Do the 5.3s come with 7.4" pushrods?
I'm worried now because a guy on here with the TEA 1.5 5.3s that I have is using 7.25" pushrods (he also has 1.8 RR...but mine are stock).
Will the 7.4s be ok? Is there a quick way to tell if they are too long? I dont have a purshrod length checker handy.

5.3 heads have the same valvetrain geometry as the 5.7 LS1 hewads, the chamber ceilings are .035 closer to the piston thus the 61.36 cc vs 66.67 chambers.
