Stamped steel rockers

I bought new mopar rockers and have already installed a Lunati Voodoo. 513/.533 with advertised duration of 272/384, in a 340 with "J" heads, 2.02/1.60 valves, gasket matched, aftermarket dual springs. A buddy back home has a comparable cam in his with stamped steel rockers, and beats on it at the track as well as the street, over 10 years now. So I went for it. I guess I'll know soon enough. Someone ask me the max lift question and I kinda got worried for a minute, didn't want to give the guy bad advice.
