Magnum intake drilling plate project

Yeah it would have been nice not to spend $80. I'll have to re read the thread to see exactly how to use this gig and it being off 1/8 inch
.
If you screw in five or six pipe nipples you will see the one that is out of alignment with the others. It's not a biggie you just put the other plate on it to drill that hole.
If you put one of the 318 steel intake manifold gaskets up against the plate you will see which hole is off also.
