Piston pin bad ?
This is not good ! All but #6 rockers are binding up when moved beyond full lift !
I spent a lot of time shimming and checked to see id there was oil com through the holes during breakin !
I did have to get replacement shafts and one rocker after inspection of new parts from Hughes... One rocker was missing the roller and the shafts ballooned during as per instruction assembly ...making it impossible to slide rockers on and off shafts !
