When does it become a get what you pay for situation? Looking to install a new set of rockers on stud mount heads. It will be driven daily and at the track with some nos I expect the power to be held to 650 to 700 hp. Just don't want to cheap out unless it doesn't matter. I'm between proforms(cheap) and comp gold race. I had a few crane cobra rockers go bad on me in the past. Thanks
