I am sorry the pic links are not working correctly, it is frustrating me. When I click on the link in the last post, it goes to 2 pictures showing the head with the holes and one showing the intake. However, to answer your question better, it is in the head-there are 3 holes, 1/8" in diameter, non-threaded and just below each of the intake ports. The intake gasket covers the holes when mounted. It is the center hole that the coolant comes out of. I have emailed Tom at Langdons and he just responded back. Tom has indicated that they are not factory drilled holes and he has no idea why they are there. Tom suggest tapping the holes 1/4-20, installing a set screw with Loctite on them.
