Using the stock LS1 Pushrods and Rocker Arms for 500hp application???
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.

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.
