<font color="green"> I'm pretty sure that the insulation is more for damping the sound from the engine than keeping heat in the engine bay. If you have that big of a problem there must be something else going on, and removing that insulation will probably not do much at all.</font color>
do you like the paint on you hood, because if you rig runs that hot maybe you need to look at something else as the problem... /forums/images/icons/wink.gif

My 454 Suburban runs 205 all the time... except when REAL cold, then a little cooler. Hood insulation is just for sound really, a little to keep the hood cool. But, if your paint bubbles or blisters from the engine heat... you have other problems to worry about. Neither my Blazer or Suburban have hood insilation anymore. Just a sponge in my opinion.
What temps are you running?

You can do some stuff to cool it down.
But first, the hood mat. If you remove it and the motor is running that hot your paint will discolor. Also, the paint will dry out and fade faster. It may even start peeling.
You can run coated headers. This will reduce heat quite a bit. Next, a high volume fan will do nice. You can also wrap your headers but that's a bad idea if it sees any water.
