Could It be The Roller Rocker Arms werent Adjusted Correctly?
If this is a small block Chevy, you adjust your roller rockers just like conventional rockers. With the motor running, back off each one, one at a time until it clacks. Then tighten it down slowly until the clacking noise goes away, then give it another 1/2 turn. Do this and report back.
