Magnum intake drilling plate project
The tap is a 1/8-27NPT
The pipe nippple is a 1/8 MIP X 3in cut in half.
1/8NPT next to a 5/16UNC
The angled hole that has the nipple on the end is what sets up the initial location for the jig. Milling the heads is not a problem. The end 2 original magnum manifold bolt holes are the reference points.
When you mill heads you may face the intake side of the head if you take a lot off the chamber side but you don't redrill the manifold bolt holes. I don't anyway. lol
