Exclamation Rocker arm trouble

Hey guys I'm drawing a blank with rocker arm troubles on my p24, put a new motor in and used a 12v block, with 12v bottom end besides cam and pistons, bought a new Hamilton 207-220, ran the truck for 20 min and broke an intake rocker. No big deal? Changed the rocker and ran for another 10 min and broke a different rocker. So I had a new set laying in the shop. Changed them and it ran for 3 pulls before it broke another intake rocker. So my question is has anyone had this trouble and found a solution?
