216 and 235 manifolds the same?

Just wondering if a 235 manifold assembly would fit my 216.

The bottom of all 216 intake manifolds are flat. The early 235 intake manifolds are also flat, and as far as I can recall are the same as the 216.
Identifying that the bottom is flat may be of more real-world use for you, given that parts get change around a lot over the many decades.
Tim's post has the casting numbers which can be used to narrow things down once you get your hands on a flat bottomed intake.

1941-49 216 and 235 manifolds are exactly the same (1941 is the first year for a 235).
These have the connection for the head pipe exiting straight down.
1949-53 216 manifolds have the head pipe connection angled towards the rear.
1950-62 235 manifolds also angle towards the rear, but have slightly larger ports where the manifold bolts to the head. They also use larger alignment rings to match the larger ports.
1950-62 235 manifolds can be used on a 216 but the alignment rings will do little to align the manifold, unless stepped rings are used.

Thanks for the info. Don't believe manifold I was looking at will work.

Mostly just need to repair my enlarged heat riser shaft holes but dread taking old manifolds apart for fear of breaking the bolts.

Heat, penetrating oil, and patience is the key to getting those manifolds separated. Once they're apart, ALWAYS change the studs and bolts before reassembling.
