Aluminum Header Adapter Flange Plate Kits
B&B Performance Header Adapter Flange Plates are designed for use on small-block Chevy engines with Hooker or Stahl dual flange competition headers. These flange plates are made from quality aluminum to save weight and to ease the task of matching the plates to the ports. They are currently available in two thicknesses, 1/2″ and 5/8″. Special low head socket cap screws are used to attach the plates to the heads, thus allowing for port matching without grinding the attaching bolt heads.
