he needs to figure out the correct rocker geometry before knowing what length studs or push rods he'll need. they make a few lengths. Depending on what type of polylock and correct geometry will dictate the correct rocker stud to buy.
I have run into this issue in the past and had to buy a different set after getting everything measured correctly.
