75 GL1000 Coolant Drip #1 Exhaust Flange...Only when cold

I finished replacing the right head gasket for the second time early this week. I have to admit the first time I did it, I was not nearly as thorough as I needed to be, so this time I cleaned the surfaces very well and used a Honda gasket.

I heat cycled the engine after I got it all back together and all seemed fine. I had no white smoke through the exhaust and no leaks. The next morning I went out and there were a few drips of coolant under #1 exhaust. The coolant is dripping from the inside of the header flange. I have ridden the bike the last couple of days with no issues. There is no white smoke in exhaust, and no coolant leak while riding. The leak happens while the bike is sitting for a few hours and is not coming from the cross over tube above the head.

I'm not sure if there is a small crack in the head or if there is something else I am missing. I am tempted to put in some stop leak since this is a budget project, but I can't talk myself into doing that yet. If anyone has any ideas, please share.

Drop the headers and see what you can see..head gasket issue gets my vote leak to
the outside of the cylinder.
Often they drip a small amount from the coolant elbow on the top of the head. It hides itself on the back side and follows the groove created by the head gasket down and gives evidence at the bottom. Put a piece of paper towel under the elbow to rule it out.and it should show up easily if this is it. If it's there, you need to try and get it on again without wrecking the oring. I have had no problems using a lubricant like grease on it.
No matter what, ...don't use that Stop-Leak crap.
There's a very particular process in using that stuff. Nobody ever follows the directions. And even in that there's still that crap in there.
Find the problem and fix it the right way, ..'cause that's the wrong way.

Agreed. Frustration is making me think of it, but better judgement is stopping me.
