What's the difference? Why is chromemoly so much more expensive than hardened steel? Would it actually be worth it to spend so much more on chromemoly?

They're stronger and lighter. For valvetrain that's a good thing.
Is it worth it? That's up to you. If you're not over 6000RPM much, I wouldn't sweat it.

I'd do regular ones, the cheesy $30 guys.

I'll go ya one better. I run the stock ones past 6500. Chrome moly: Good for use with strong valve springs and high lift cams. They flex less too.
It depends on the application whether they are a necessity or a waste of money.

Yea, I'm still using a mix of 305 LG4 and 350 pushrods. They weren't bent so....

But I figured if you had your heart set on buying new ones...

Hmm.
I'll be running high lift but won't be spending much time over 5800. I guess the hardened steel will work for me.

Thanks for the info. I searched a long time and did not find this answer. Now it should be easy for anyone to find.

Chrome-moly is stronger than most other alloys, so you can get the same strength with thinner material, which ends up being lighter.
