Dude, they will be gone with your first mis-shift, I broke 2 and bent 3 before my cam and headers with the stock 6200 rev limiter.

I think the key word is "mis-shift" in that last statement.
The stock pushrods, actually are not that bad. The problem is the shitty springs that they are married to. As I'm sure you know, the stock springs float at high rpm. This leads the valve contacting the piston, and pushrods go boom. The pushrod ends up getting bent, but it is really not its fault. It is just getting a bad rap because of the shitty springs it has to work with.
If you are not having valve float problems, then I don't think you will have problems with the stock pushrods.
I raced on stock pushrods back when I had a 918 valvetrain. True, the doubles are going to have more pressure, but I don't think you will have a problem.
Good Luck

Lingenfelter reuses them in nearly every single application. The key is the valvesprings. Go throw some hardened pushrods in the car with stock springs and go miss a shift. The pushrod will not give, but your valves will. LOL
I would go ahead and change the pushrods out just for peace of mind.

ok so with the m6 trans. stock rods would be best if you ever miss shift they would be the week link saving the vales ect.
with hardend rods and a miss shift kiss everything good-by.
thats what i'm getting from all the posts here
correct me if i'm wroung here {not spelling}
would'nt i want a weak link that would'nt cuse to much truoble in the end?

the shop that did my heads/cam package even recommended against having hardened pushrods saying its best to have the stock pushrods as your weakest link, and that hardened ones will make something else (more expensive) be the weakest link.

Had a shipping mishap and I ended up having to use stock pushrods with my heads/cam package.
How long are these going to last??? I'm going to be ordering hardened ones but want to know how long I can put it off??

Any idea if non hardened pushrods of varying lengths can be had? I may need shorter pushrods, but don't want to run hardened ones if possible. I'm running Rev dual springs in my heads.
