I`m running a 1961 "235" in my 1950 Chev Coupe.
I swithed out a 1950 "235", using the original 50 intake and exhaust manifold, so, I do not know if their is a differance between the 216 and the 235 manifolds.
I got rid of the "alignment rings", used the new gaskets which I "stuck" to the head with high temp gasket sealer. Everything works good.
You really don`t need the Heating chamber, most of them have the heat "Rizer" rusted open anyway.
We just made a plate to block off the heat chamber on the "Fenton" headers.
