Hi Guys, I have a BBB BullDog head that is bare, no seats, no guides. It has two (2) porosity holes in it that can be pretty easily welded up. They are in each of the outer most upper and lower bolt holes as you can see in the pic's below. I originally had gotten this head to "play with" on our bench and see what I could make it do flow wise. It's been sitting for a couple of years now collecting dust and looks as tho I probably won't get around to it any time soon. I paid $250.00 for it. How about $175.00 O.B.O. plus shipping. It's a later casting in that it has the ribs and the "BullDog" name cast above the center exhaust runners. Would be great for someone who wants to try different things on before doing anything on their good set OR can be repaired and have as a "back-up" head. :TU: Pic's for your viewing pleasure....please ask if you think any more needed!
