Need some help...

[AmunRoo]

I'm replacing my head gaskets and while I'm in there I'm going to replace the lifters and push rods. Can anyone confirm the stock push red length? As far as I can tell it's 7.400" unless I'm incorrect of course.

I have the L92 without AFM.

As always, Any help is greatly appreciated!

7.385" to be accurate, but many just say 7.380". Most aftermarket rods are 7.4". Maybe when stock rods are advertised, their length is rounded up? If they honestly are 7.4", I'd imagine they'd be fine since the stock lifters have quite an acceptable range for preload.

Also, most aftermarket performance cams have a smaller base circle (usually .050"), so a .025" longer push rod is needed to maintain stock geometry. 7.380"-7.385" stock length plus .025" is 7.405"-7.410". Since aftermarket rods typically go in .025" increments, an even 7.400" is the nearest without being too long.

When I replaced the cam and lifters in my 2007 Denali with the 6.2, I looked at push rods in case I had some that were damaged. What I found then was that 7.397” length was shown as stock replacement length. All the rods I pulled looked good and went back in with a stick cam and lifters so I never actually measured one so can’t confirm 100%.
