Not sure on the hinge pins, but on my car, the way the hood fits, i need a different thickness of cowl lacing at some points than others to make the hood fit nicely along the cowl... i just have a dense foam rubber strip on mine, with a second piece underneath the other one in some spots to act as "shims" to make the hood line look better... its still not perfect, but you'd be amazed at how much height adjustment you can get out of your hood to cowl by playing with the seals...you can get the foam stuff from a body shop supplier, they have a catalog of 100s of different widths and thicknesses, with or without adhesive back.
