It depends on which 235 you and the seller are referring to.

It should bolt to any head but the intake port diameters changed over the years. The 216 and early 235s had smaller head-to-intake-manifold port diameters. Some people have posted that they have used an older intake manifold with the newer 235/261 heads.

Also, I think the distance between the carburetor bolts on a 216 and a later 235/261 (1954-1962/63) is different. Since 235s were available from 41-62, most likely the seller is talking about an earlier 235. I do not know when the 235 carb-bolt distance changed (maybe in 1950).

Ask for a measurement of center-to-center carb-bolt distance and compare it to yours (if this is important to you and your carbs).

The 216 and early 235 engines are not "splash oilers" -- this is a splash oiler.
