Thank's Sparky, It turned out to be a pretty simple fix, we ground a relief into both sides of the lifters from the lifter oil holes down to match the oil galley hole.
We had bought and used identical lifters before we installed our Jesel rocker system and had never had a problem other than wishing we had given a little more clearance allowance in the bores.
When we honed the Dart (Big M) block, I called both Dart and Comp Cams and neither would commit to giving us any guidance (the old "its up to the engine builder song and dance", but neither he or I had any experience with a motor meant to do what we are asking this one to do.
What essentially happened is that through lack of oil through the lifters, the push rods did not receive enough oil and it ate the top off of several exhaust pushrods and damaged two Jesel Rockers.
I had allready pitched the earlier lifters which were galled so I can't tell you what was different about the oil location, but it was another expensive lesson for a novice.
