Jordan, I would suggest that your engine is a 40's something build which would mean it is a 216 c.i not the 235 blue flame. They require different gasket sets. The way I tell is via the side cover. The 216 side cover goes right up to the rocker cover and the spark plugs go through it where as the 235 has a short side cover ending level with the head gasket. Also the rocker cover on the 216 has 2 central posts with nuts on top to hold it down where the 235 is held down with I think 4 screws around the edge. Hope this is of help. Can any one else confirm?
