Ken,
FWIW I recall putting a little more torque on that back bottom bolt
when I did the headgasket, 68lbs, only because the side of the bolt
felt like it was binding on the head as I was turning it. I don't
recommend that much torque but mention this because Philippe said he
experienced the same binding on the very same bolt with an xn6 head
that he did recently.
Also mine had had the headgasket done once (badly done) before I got
the car and it had the telltale trickle of coolant back by the #1
cylinder.
I think you'd be fine going to 65lbs to try and get that leak to stop.
Brian Holm cautioned that when doing the retorque one should drain the
coolant from the head so it doesn't seep between the head and gasket
when you loosen the bolts. I wouldn't use the Barr's leak.
One last thing which you might not appreciate hearing at this point but
in the 1988 service bulletins they suggest using a light coating of
'high tack spray gasket material' made by 3m on both sides of the head
gasket when doing xn6 head gaskets for pre 86 cars to stop seepage.
