What effect does the insulation have on keeping engine heat out of the intake and therefore the intake air?
Could removing the insulation make the engine noise more pronounced while also heating the intake air???

This in combo with the Grille and removal of the hood weather strip has reduced my temp 25 degrees on track under load. Also this is with the rear piece still in place, I just removed that and have not tracked yet. I am not saying the foam alone worked but has worked well in addition to the other mods.
I highly doubt the foam keeps anything cool but does trap heat. I have touched the inside of the valley and it gets hot very fast even at idle.

Yes that won't help keeping the heat off the manifold. I saw a picture of the 5.0 foam and thought it filled the whole cavity up to the manifold. That sure isn't what you're describing.
I plan on insulating the bottom pan on my supercharge when I take it apart in a couple weeks. I am going to cover it with aluminum covered insulation and then gold reflective film.
Ok , let me have it !! All comments are welcome.
It's there for insulation of the intake charge from radiator/under hood heat.
"The foam pads limit the amount of engine heat that gets to the manifold by blocking the front and rear openings at the engine valley."

Lol. Are you sure?
Sorry for the dead link in the quote.
As for the rear bulb seal...leave it. If you don’t believe me, take it out and test it with yarn tufts in the top and bottom of the hood.
I don’t have hood vents, but did remove the outer 6” - 8” or so off the ends...after a bit of testing.
