The Stovebolt Site Forums The Shop Area Engine Shop 216 Intake & exhaust manifold on 235, will it work

I'm running 216 manifolds on my 235 and not using any adaptor rings.

When I first assembled it I used the adaptor rings which are essentially shortened 235 alignment rings. They seat nicely in the recess in the head's intake port. Then the 216 alignment rings seat in the recess in the manifold and slip into the inside of the adaptor rings in the head.

I was worried that the 216 rings had no seat or step to prevent them from going too far into the head.

After sleeping on it I couldn’t get the thought of the 216 rings slipping down into the intake ports of my head. So I pulled the manifolds off and glued the 216 intake manifold gasket to the manifold to assure alignment and re-assembled it. The engine runs fine
