Quote: how do you attach your intake manifold jig onto the magnum head?
If I remember correctly, the 1st one (that got to travel) was alinged by some type of L-bracket, and clamped in place with large C-clamps. Wouldn't be hard to install a couple of locating pins that lined up with existing holes in head, to make sure was in correct place before drilling. We have quite a few people that are interested in this it seems. I'm still interested in it!
