Z06FRC

I'm wondering if I should use the stock LS1 rocker arms and pushrods for 500hp application? If not what can I use that's mainly for street use? I'll be running Patriot Performance 64cc Heads with Comp Cams Xtreme RPM High #54-424-11. My car is a 99 Corvette FRC that I daily drive in the summer and once a while take it to the dragstrip.

The stock rocks will do, but I would get a set of hardened pushrods for $110.

You will need to get hardened push rods and stock rockers should be fine. Its up to you though if you want to upgrade your rockers. It certainly wouldn't hurt.

I would upgrade the pushrods for sure. You can get a set of chrome moly pushrods from summit for like 87 bucks. You can keep the rocker arms but, if you upgraded them it wouldnt hurt anything probably gain you a couple hps.
