Sorry, I missed the fact that the application was for a V-8-60. I did have an accessory manifold heater for my V-8 '34 Fordor but recycled it due to poor condition and the concern that I could not inspect it well enough to insure that I would not be breathing exhaust gas. I prefer hot water heaters for the early V-8s. There are many to pick from.

To answer the question for a picture of the Model A Autolite, it is below. It has been my experience that there must be at least three different patterns used for casting the exhaust manifolds. The varience is in the depth of the fins. The deeper the fins, the more heat transfer. Gar Williams
