Insulated all of my hi performance engines on my bugs when I was running
them.  Cant say it did anything for noise but it kept the heat from the
exhaust away from other things.  As for the heat seeping into the van after
parked...nothing other than a really heavy isulating of the firewall and lid
area will do anything about that.

On the bugs I had a double layer firewall with a cover of sheet metal.  Both
for heat insulation and sound insulation.
