Paul, thanks for your input. VERY VALUABLE those alignment rings are you have :wink: . I would advise hanging on to them. When I had my first Chevy, it had a 270 head with small intake ports. I had purchased a Clifford Performance manifold which had large ports, alignment rings WERE NOT included. So I went to Burbank Speed and Machine, saddled up their lathe and turned out 3 alignment rings just like what you have pictured.
Later when I found a large port 302 head at Barstow Truck and Equipment, I used the correct rings. The head that is on my engine now is a 302 large port with matching intake. This combo is what will remain in place for as long as possible. I have the carb. in this thread soaking in water/pinesol solution and a rebuild kit on the way. Until I get a Rochester 2GC and adapter from Buffalo Enterprises, I will try my luck with it.
Again, thanks to both of you guys for your participation. All input is appreciated and valued. :)

Hey Dave,

I got the adapters shown years ago from some other Chevy guy. I searched ebay and there are some available. Just search "216-235 intake manifold adapter ring" and you should pull them up. Wish I had them available to make some measurements, but they are installed on my 1941 truck right now.

When I machined the adapters for my truck, I cut a funnel shape into the "approach" from the manifold. When the ring is installed, there is a very evident step inside the intake which causes airflow cavitation and loss of intake performance. Again, they're not needed for my engine as I have matching intake and 302 head with correct alignment rings installed.
Everyone else who is interested, here is the link to ebay page with the parts in question. https://www.ebay.com/sch/i.html?_from=R ... g&_sacat=0.
