Pre 68Dave,
what do you do for a carburetor in this setup? I am going to guess that you rejet a 216 carb.
I have a steep hill I test all of the 235s I work on and I have seen no adverse affect from running a 216 carb. with 216 jetting.
From 1941-49 the big trucks with splash 235s used 216 carbs and manifolds from the factory.
Don, I make my own alignment ring adapters but I know a lot of people leave the rings out.
I would glue the gaskets to the head to keep them lined up, and center the manifold , if your not using rings.
