Another question: Are you using a stock Model A distributer? With original points? I have 2 stock distributors I use. One has Model A points and one has modern points. I don't see much difference in performance.

Not doing a failure analysis is a sure way to have a repeated failure. We did a very extensive failure analysis, but didn't come up with anything positively conclusive. I think the most likely cause was the water passages on the new 5.5 head were not properly drilled out from the factory and did not flow water. That head has now been replaced. See the post "Help on Overhaul Failure" on this site to see many of the things that were looked at.
