Hate to ask value... Model A police-B head

[31deluxe]

I have been told I could have and engine that had been modified back in the 60's. I'm told it has a pressurized oil system. but the interesting thing is it has a B head on it. ( four stud water pump). I don't know if I want to mess with the engine assembly or if the head is worth anything. Thoughts.


I will try to get a picture of it soon
