I asked Tom if I can space my rocker arm studs a bit to gain some thread engagement, just waiting to hear back now.
Then you will be reducing the thread engagement of the stud into the rocker bosses if you space them. You need a rocker stud that is longer on the rocker arm side to provide more engagement of the adjusting nut. Since your using longer valves, and now longer length non-stock pushrods you also have to use longer length rocker studs, especially if the rocker stud bosses have been machined down also.
