Have a look at the ports? You should be able to easily tell the difference between a standard and modified head at the very least as the standard one will have the rough sand-cast finish still
Does'nt mean it's definitely a Longmans head but you will know it's not a standard one for sure.
Did'nt most of them have a little plate on them with a number?
