The lifter hole info is great - comparing a stock lift cam to your new cam should give you an idea of where to drill your hole as you look at the groove in your lifter. What I have been taught is to get one intake and one exhaust valve set up with your adjustable lifter and set the rest to that measurement to make your adjustments that much easier/ closer to what you need for the other 7 cylinders. I might be stating the obvious to most who have done builds but I figure I would throw it out there …
