Coolant Crossover Tube Seals
 

Hey,
I see that combination motorsports includes these with their gasket kit for cylinder head swaps. I wasnt planning on replacing these seals, and honestly dont remember seeing where 4 seals would come from. Maybe someone can clarify this for me, and are these a necessity???
Thanks,
Brandon

Two crush washers per banjo bolt on the coolant cross over tube. I would highly recommend replacing them.

Edit-This is where they go.
