If you want to use your 216 set up it will work fine. I have done this many times. I just make adaptor rings and tap them into the head to shim down the size for the 216 alignment rings. I have a long hill I test engines on and a 235 with the smaller 216 setup seems to make very little difference. 1941-49 big truck splash 235's used a 216 setup stock.
