hedman "tight tube" hedders?

does any one know if these will clear the Z-bar on a 4speed? just what I needed, one more thing to add to the list of things I want to get for my car, if only money was no object!:violent2:
Plenty of room to clear the Z Bar................You will need to route your down pipe on the drivers side under the z bar off the header collector. Piece of cake.
