Call them and check, but I think the standard 9.130" works.

Regardless of what is posted, I'd STILL check for myself.

Like Lee said check them- too many variables different lifters have different cup height, milled head/decked block affects it even different brands of rockers affect it.

Wont the type and make of lifters matter on pushrod length?When I went from Isky solid rollers to comp hyd rollers I needed a 1/2in shorter push rod.Tom

Check the length!Back in 2009 I was about to order my pushrods,I compared length with a fellow member who had the same cam,lifters and so we thought the same heads.We both spent a few hours trying to figure out why our calculated pushrod length was so different.It turned out my heads were setup different with a shorter valve.At the time we both had SD 290 cfm KRE heads.Don't assume anything!

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
