Here is what the Autolite Waffle Manifold Cover looks like, best I ever used and I have tried a Couple of different stlyes that were mentioned above.
That is a generic door for many types of heaters. Rather than messing with a one size fits all, which they don't, I would prefer to have the correct part. The hunt goes on.
This is a cast iron waffle style Goerlich's model C heater made in Toledo, Ohio. The second picture is an Autolite heater on a nicely detailed engine. The Autolite, if I am reading the casting correctly, was made in Fostoria, Ohio ? which is about 40 miles south of Toledo. Interesting, must be cold in northwest Ohio.
Ive never seen an intake like i the first picture.
Was the vaccum port added later?![]()
