My manifold had 2 bosses cast into it. These needed to be drilled out and appropriate fittings installed. You should pick these up in the attached photo.

Also the second photo shows how high I fitted the header tank. ie, well above the top of the heads

THe large braided hose is the fill line to the rad pipe, the small braided line is the bleed from the rad. The clear hose is the overflow - presently just to the ground as I have not worked out a catch tank arrangement yet.

Hope the photos help.
