push rod length
I just installed a new cam in my camaro, there is about 1/8 inch play between the rockers and valve springs after everything was torqued. Do i need longer push rods? I was told stock length pushrods would be fine but i know this cant be right.

from what i understand its all about the base circle. if its smaller than the stock base circle then if im understanding all this right it would require longer rods. im in the same boat as you so im hoping someone who knows for sure chimes in.

yes, you need longer p-rods. not not sure how longer p-rods from 0 lash to get correct preload on lifters but, I'm sure some one can help on this. take a reading on gap with feeler gage. use those numbers plus whatever reading for correct lifter pre-load. or just buy a measuring p-rod.

01 LS6 0.760 (19.3)
02 and up LS6 0.748 (19.0)
specs from the book "How to Build High-Perfromance Chevy LS1/LS6 V-8s".
