From what Clark described to me is that Mike was going to use OE Z33 lifters and do his own machining to his cylinder heads and do some one off stuff so he could get these cams to work for his personal agenda. Clark made it very clear that they would not warranty any of those camshafts if they got damaged as it wasn't something he was 100% sure on. It was a favor from Clark to Mike. What is Mikes contact number as I'd like to speak with him personally as there's quite a few things I need to ask him.
