[QUOTE="Bgdiesel, post: 1522272, member: 5612"] We don't degree any of them as of Rt now because of the stock cam gear design and from what we have seen they should not be having piston to valve contact. It is my opinion that the valve springs do not have enough seat pressure, so we do shim every valve spring that comes through the shop on a 6.0/6.4 to 100lbs seat pressure and we no longer have any piston to valve contact on any cam that we have used. As you may already know the stock pistons and valves touch quite often, on hard driven trucks or after engine mods and programmers, obviously more of a chance after any head or block machining I do like to run minimum valve recession of .030" on every head that comes through the shop we also bring every new head from ford straight to our machine shop and resurface it and set to the same valve recession spec as well. I know this spec is outside of the ford spec but I don't really agree with that particular spec. Side note, the race truck runs no valve reliefs whatsoever without any valve contact and we are not milling down the top of our pistons currently Sent from my iPhone using Tapatalk [/QUOTE]
