We had a recently rebuilt Pontiac engine come through our shop with Scorpion rocker arms and a HFT cam. I think seven of the rocker bodies were cracked around the front side of the trunnion area. The worse part of the deal was Scorpions unwillingness to help resolve the issue. The tech at Scorpion didn't seem to the the cracked rocker bodies were an issue since they're rocker arms bodies have a lifetime warrenty. But insisted the rockers are sent back by the shop that originally installed them.... We put HS rocker arms on and called it a day.
Next issue we had was with a new set of 1.65 Scorpions that had excessive run out on the roller tips making it impossible to adjust lash. Over half the rocker arms had .003 or more of run out.
