No, not really....They will all physically bolt up to the heads, the exhaust pattern is the same. The heads are raised a good deal, they are also a good deal wider than a stock type or Indy head. Lastly the exhaust port on a B1 once ported are very large, most shelf headers will not be big enough to cover the opening. But I have seen TTI's and Fenderwell headers run with B1's. I am gonna assume those heads dont have a ton of port work though.

If it helps not sure it will here are my headers. The openings in the flange BARELY cover the port. Note the area around the flange between the port opening and the edge of the flange. BTW those notches in the flange are for head stud clearance.
