Adj. Rockers // PICS & ????

i wouldnt say thats entirely accurrate. maybe with hyd cams, certainly not with mechanical cams and adjustable rockers. you cant change the height of the pivot point (and therefore the contact path of the tip) if it's really off without shimming or other fixes, but you sure can change the angle the rocker is on with a longer or shorter effective pushrod length. Not drastic changes, but saying "has no effect" is a little misleading.
