One of your O-rings may have rolled over on you and not be seated properly or possibley you might have something under the shoulder. Not sure if you would want to pull it again to check, you'll probabley need new O-rings for sure if you do. I think I would try to get it to sit to the same point as the others by using 2 or 4 bolts with big washers in your head bolt holes and cinch it down at the very least. Not easy to put preasure on water side with out head on but you might also first before any thing else want to at least put some water in to see if you have a leak when looking up from under side. That might give you an idea if your O-rings are okay. Is it normal, I don't have enough experience to tell you but when I rebuilt my 1550 I had pretty much the same situation,# 6 last cylinder at back if I remember correctly and I did what I have suggested to you. Still holding about 800 hrs later. Sure there are others out there with lot more know how than me and You'd probabley be wise to wait for their input. Just giving you my 2 cents. I had never rebuilt a motor before that and was worried and ancious about the end product. Hope this helps you. Rocko.
