You could try a good stop leak and that may solve the minor leak there.
My 5.9B head gasket started leaking there when I was on a trip and I stopped mine by cleaning out that area as best I could, scraping out in that seam as good and in as far as I could get in there. then I cleaned the area with brake cleaner and being parked at a deluxe site at Walmart, I got a roll of tank sealer epoxy, mixed it up real good then put it in the crack and used a screw driver to drive it into there as much as I could and let it cure overnight,
Some might say this is Mickey Mouse, but I was on a 6,000 mile trip. That was ten years ago and it hasn't leaked since.
Oh ya, after the trip, I re-torqued the head bolts to 125 ft lbs by taking one head bolt out one at a time, cleaned oil lubed the threads.
