Take a look at my 35, The one that is in the car is a 207 and the red one is a 54 235. I think you can get kits to have the bolts come through the valve cover and use a 216 valve cover. There is size differences in the engines though the 207 is 1.5 inches longer than the 235.
I have had a dissussion with a engine swap on the 207 to a 235.
