When I did my hood with the Switch Suspension hinges, I basically installed the fender bumpers and cowl seal, and then set the hood down on the fenders. I centered it up and adjusted the bumpers as needed to get the hood where I wanted it without any influence from the hinges. Underneath, I already had the hinges installed without the gas struts and with the weld on bracket centered up on the hinge. I then just pushed the hinge up to the hood and tac welded the bracket to the hood. It is only the weight of the hood that keeps it in place so as long as you position that correctly before welding, then the hinges will set the hood right where you want it when closed. I think the only thing I did have to do was shift the hood forward a bit on the adjustment because my initial placement of the hood was too far back, but that was all my own fault. Hope this helps!
