Picture time, once again. Despite have quite a few 7.3s in the family and working on several others as well, it's the first time I've had a cylinder head off. In the process of getting the head real clean I noticed some machining. Anyone know if this is an OEM head surface? Supposedly rebuilt about 20k miles ago, so it could have been resurfaced sometime. With all the tractors and other vehicle heads I have never really seen anything like it, in fact I can lightly feel the machining with my finger. I've been taught that if you can feel something on the head or the block, it isn't clean enough yet. Unfortunately I can't really scrape that off... lol. Probably going to call the machine shop in the morning to get an opinion too. Might post on a higher traffic site like PSN, but thought if any vistors here could chime in that'd be great.
