Title: Head Gasket Question
Post by: koyota93 on June 02, 2009, 11:02:35 PM: I am not sure if I have the correct head gaskets for my BBC. The block is 3999289, Mortec says 71-79 2 Bolt 454. I have Fel-Pro gaskets 1037 and it says for blocks with 3 lower coolant holes in the block. Problem is mine only has 1 coolant hole. Are these OK to use or does anyone know the correct ones I need? I am trying to get the motor together and get on the water soon.
