Question about using stamped rocker arms

No way would I try it. I had the Lunati 60404 cam in my old 360 and my springs were a little lighter than yours and while the pushrods didn't punch throuch the rockers it ate the tip of them where it scrubs accross the valve stem. Had stainless valves so they didn't give, just chewed up the rockers. Lasted about 9000 miles and they were junk and they were the Mopar perf. rockers.
