Tim,

The 1953 235 engines were "odd balls", so it is best to check to see if the head-bolt patterns are the same. If they are the same, they are interchangeable (except the 1953 head will not have the four holes for the 54-62 valve cover).

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