i was inspecting the head on my 400 and noticed some wear and scuffing where my cam sits (not where the bearing sits, the other spot) is there a way to fix this like building it up and re-boring it or is it screwed. i would hate to put my new cams in and have them only last the summer.

had the same problem with my 98 400f. engine dynamics fixed my cam, cam journal and cam cap for 120 bucks. dont forget to shim your valves when you get your head back if you go through them
