I have a 44 A just got the head back from the machine shop.. my tractor did not have a head on it when I got it. So I bought a head and tappet assembly upon dry fitting the rocker assembly I noticed the oil outlet washer is no where close to lining up with the oil inlet in the head. It is about 2 inches off. I made sure the rocker assembly and head I have are correct for my serial number. Anyone have any experience with this? Also the oil outlet washer I have has a mark on it from what looks to be a washer that used to be there but my parts manual doesn't mention anything about any washer.
