Joker, If you are looking for a 848 head go to Bishop Engines in Oak Clif. That is where I bought mine for a hundred bucks. I put it on my 54 235 and it works great. By the way when I got mine they had racks full of them and you could pick the one you wanted. They garentee that you will not get a cracked one but they won't pay for the magnafluxing. Hope this helps.
