The trap of the industrial / motorhome 318-3

I had a 1977, 37' Foretravel RV 440, peanut plugs heads..... ain't sure about the water pump I think I would have noticed that as being an oddity

Those heads were a 452 casting, but with more water passages than a car head. Cant remember if the spark plug was moved on those or not.
