Would there be any thing that could be done to a Heat Riser (presently working) to assure it does not freeze up. Being as how it is in the manifold I guess that it would be useless to oil it. I would feel more comfortable doing something instead of ignoring it and wondering if or when it will freeze. Anyone have any thoughts?

Driving your car regularly should do it. I'd think the normal movement during the warm up - cool down cycle would keep it free.

I don't think that I have ever owned a 216 engine that the heat riser was't stuck (in open position, of course). I wouldn't worry about or with it. They seemed to run quite well without that device working properly.
Just my take on it.

each time that you service the engine work the heatrizer by hand full open to full closed and back to full open after the engine has cooled down to room temp.

For best engine performance, the hear riser should be loose and operating. Why else has every engine had one for so many years.
Yes they will work with a stuck open one, but it is not how they should be run.
Spray a little PB BLASTER on it once in a while, then move it open and shut a few times.

Check the May 2009 issue of G & D. An irreverant trouble maker named Ray wrote a tech article based on his experiences with his '36 Chevy pickup that covers this subject and some others as well. The siezed heat riser subject is in his article.

If you're like some of us and can't find that G and D, as long as it's
not "stuck," you could move it up and down by hand now-and-then. That
should keep it functioning properly. A "working" heat riser will provide
better performance and economy also....
