Perkins didn't do a 50hp engine for cars so I'm guessing this is a boat engine.
It is is a perkins prima then the above advice is correct but the orientation might be a bit confusing in a boat. The timing pin holes are facing away from the injection pump slighly lower down on the opposite end to the cam belt.
