Can they be ran? What wall thickness is necessary? Solid roller that will see max of 7500rpms, and there is not enough clearance to the lifter bores for a 3/8 pushrod (A 3/8 will rub the lifter because of my offset intakes)...Is .105 wall sufficient? Do I need .120 wall?
Springs are 250 closed, 600 over the nose, and the pushrods are going to be 7.750" long
