West Valley G,

You called it. I think the leak is coming from that cork gasket. It is seeping very slowly (now that I want it to leak).


Back on the head and spacer issue...
I was looking at that again yesterday. I may have created my own problem.
Before I installed the head, I had watched an online video in which the guy used the stackup shown in the sketch "current hardware stackup" in the attached pdf file. So that's what I did.

Question: Do you guys that have heads with studs use a double nut stackup (nut - spacer - nut)?

It is probably not an accident that the spacer height is the same as the distance from the boss to the top of the fin. So now I'm thinking maybe the correct hardware stackup is what I sketeched in "solution #2". I only wonder why Kohler wouldn't have simply changed the boss head height to bring it even with the top of the fins?

EDIT: I think the pdf file was too large and it didn't upload the first time. I reduced its file size (and its quality) and re-uploaded it. I also attached a photo of the sketch. I don't know which is easier to read.
