Why? Because I could find one and it didn't cost me 2500$ like a fully rebuilt from Brewer's ... And I've got a cast iron block, heads and crank, so I'm not really at 40 pounds more or less now... oh and i'm not building a pro touring thing either so i don't really give a f... :)
would liked to have seen you do a little smooth up and bowl blending around the exhaust seats. you would be surprised at how much diff. that makes on a flow bench ! even a little finger nail clipping size ledge around the seats shows up big time !
