I will be installing a 216 intake on a 57 235 so I can get the carb to set level.
216s and 235s both set the carb the same, level on the angled engine.
The bolt spacing for the intake to exhaust is different between 216 and 235 so you must use as a pair.
216 manifolds up through 1948 have the exhaust dump straight down. all 216 and 235s after that angle back.
