Pitman arm is hitting tortion bar! Help?

Its a 340 motor...bored .30 over. pro comp cam..j heads with bigger ports..flat head pistons. I think im going to call Schumacher monday and see when exactly those headers are going to be done because they would work perfectly.
Give them a call and since they are still in testing offer to "test" a set.they may be interested with your engine setup.Couldn't hurt.
