I have a 7.3IDI that I built a few months ago with upgraded injectors, pump, and cam from R&D, as well at ARP head studs, dual valve springs, and the stock turbo system. I just took the engine apart again because it was making some noises I wasn't liking, and what I found was that every single exhaust valve was hitting the pistons. I don't have reason to suspect the cam is out of time because it ran perfect and made tons of power.
I realized the problem was that I bought the engine dissembled, and the guy I bought it from said he got the heads decked, and I didn't think anything of it at the time. So it was put together with a regular thickness head gasket and the higher lift cam.
My questions are, what is the stock deck height on the heads and block and how do I measure it? I don't know how much has been milled off. Also what are my options for thicker head gaskets or head gasket spacers. I know I can get my pistons milled, but I need to know if that will take off enough to clear properly.
I am already going to send the block to a machine shop to get at least one bore sleeved as one bore is badly worn and was piston slapping.
