Thanks for all the responses.

I changed the head gasket to a “Best” brand copper gasket. Followed Brumfield guide (again), and even slathered the gasket with grease. So-far-so-good. I am using straight water for now.

I believe Dave in MN nailed it, tho. I admit I do lug the engine. I don’t live in a hilly area (Chicago), but I daily my A, and our heavy traffic creates moments where it is unavoidable to lug the engine almost every trip. I theorize that the cylinder pressure experienced with my combination head/timing/etc, is so much higher than the A was ever designed to contain that I am pushing the head off the deck enough to leak coolant. I don’t believe this is avoidable with my current set-up. Hear gasket choice is irrelevant.

Also, I did discover that I was leaking coolant into cylinder 1, and 2 during this period.
