I've used this fiber/foil stuff. http://www.lesliewong.us/2007/08/25/hood-insulation/ It's very effective, but may not meet your aesthetic requirements. I've seen a Dynamat hood liner product also though I never tried it. The original foam, or something that looks like it, is probably still available, because the oem stuff is still available for the '72 BMW.
I think it's not only for sound deadening but for heat insulation. Before I installed it on the BMW, the hood got very, very hot from the engine heat.
