LA intake magnum head questions

My jig is for drilling the heads, sorry for the confusion. I bought a 1 1/2x1/8x48" peice of flat steel stock and some 5/16" id x1" long steel spacers (to match the drill bit size). Used an old intake gasket to mark the steel, drilled it, used some bolts and spacers to hold it in place, put a bolt in to find the anger that the bottom of the spacer needs matched to, and tomorrow I will be welding it up. I will have 2 peices that go underneath the head so i can use the head bolt holes with a long bolt/nut to hold it in place. Also a peice on each end to bolt to the magnum accy holes.


I've been thinking about this since discussing it in the other thread. Guess I should have mentioned it sooner, but do you want to give my jig a shot?
