Small Block Chevy Adapter Plate Kit with Gaskets fits Lightning, and Most Over Transom Headers 

Small Block Chevy Adapter Plate Kit with Header Gaskets

This adapter plate and gasket kit, made by Hardin Marine is used with Small Block Chevy Lightning Headers, or Over Transom Headers such as Bassett or Rewarder Headers. When replacing the adapter plates and gaskets on these applications you'll need these plates, adapter gaskets and a standard Small Block Chevy Exhaust Gasket, so we created a kit package that includes all four gaskets and the plates. These are high quality original equipment style gaskets die cut to exacting size and shape for the perfect fit every time.
