I have never had a Model A with a heater. I didn't want to cut up a firewall and I don't like the look of the hoses in the engine compartment. That's just me. But most importantly, if I drive for over an hour without the windshield cracked a bit, I get a headache. I'm sure it is carbon monoxide poisoning, just a slight amount. I don't think you can get an absolute tight seal at either the manifold or at the exhaust clamp. That is why in the early days you brought a lap blanket with you! Ed
