I have a couple of pairs of new Crane rocker arms that I was going to sell, but now I have no idea what they fit. The offset is about 0.300 inches which is more than stock, but much less than Victor or Indy heads. I thought maybe Stage V or VI but it doesn't appear to be the same. Maybe B1-BS or something like that? Anyone know what uses a 0.300 offset rocker arm?
