Drilling Magnum heads for LA intake pattern
I don’t have the pic of that but i can get it. I welded a 1/4” rod at the bottom to lay up to the head to align it square to ports then simple vise grips to hold it in place. I did two holes the used bolts to hold it but not needed. It’s aligned side ways with the scribe line off the existing bolt holes (LA and Magnum are the same spacing)
