I though I was ready to drill a bleed point at the back of my Performer inlet manifold, but now am not so sure. I see from my photos there are blanked holes there in the standard CI head, but open passages in the my new performer heads. Now I am not sure if there is a water passage running across the manifold from head to head since I didn't take a photo except from the top of the manifold. I searched and found threads on the subject but not explicit enough to be sure. So can someone enlighten me as to where I drill the hole(s) and whether the drillings go into a passageway in my performer manifold, or through the manifold into the head passage?
thanks
