Butler Performance Brass Freeze Plug Kit For Cast Iron Cylinder Heads BPI-1021

Brass freeze plug kit for a pair of Pontiac cast iron cylinder heads, 1965 and up.

Head plugs are not block plugs, but they get replaced in the same pass and they are the ones people forget to put on the order.

Heater hose fitting not included. Add AAU-P132N if your passenger side head takes the press-in fitting, or order BPI-1022-HHF to get the kit and the fitting together.
