Which push rods are lightest? I reused the stock ones because I ran out of money. I figured theyd be easy to change later. Everything seems to be ok but it still has the stock rev limiter. The valvetrain is pretty noisy though.

The noise valvetrain could be any number of problems. How much pre-load is on your lifters? What's the basecircle diameter of your cam?
As far as the 'best' pushrods, Comp's Hi-Tech line of pushrods would be good for your application. Anything by Smith Brothers, JESEL, Manton, or ISKY will also be very good, even on the all-out race stuff.

Comp even has a 7.375 now.
Just wondering

Most valvetrain manufacturers will have good technical write-ups on valvetrain geometry on their webpages. That's a good place to start, even though it's all pretty basic stuff.

If they bend, that means they flex, if they flex they are robbing you power and induce valve float.
Darn, I wish poeple quit refering to the stock p-rods as a fuse
Also stock p-rods are 7.38 in length and aftermarket cams are .03 smaller in base circle, so unless you have adjustable rockers, you're valvetrain geometry is out of whack by .03, and that my friend makes a noisy valvetrain and again a loss of power and worse if your lifts are pretty decent.
Sorry but please QUIT referring to stock p-rods as a good fuse.

So you can show me ACTUAL dyno results of these power robbing push rods?
Fuse or no fuse im not trying to be a dick here. Im not Mr. KnowItAll, nor do I pretend to be. Im simply finding/asking new ways to do things. Dont be afraid to think differently.
Never did answer my question on what exactly is going to cost more...
