Killer hood!
Everything alin said, and to build on it:
I never did it personally, as I never had the intake manifold off. But legend has it there's a coolant pipe that runs right under it (

You can also get a heat chimney integrated with a heat shield, to direct heat up and out.
Radiator guards can help channel air through, vs around the radiator (

Of course there's always more drastic solutions such as FMIC and/or AWIC.
You can get some sort of cryo2 system for on-demand cooling if you dont already have an intercooler sprayer.
If you do have an intercooler sprayer, there are many different options for automating the spraying so you don't forget to do it.
I never did the DEI heat tape, but people have reported good results. A few years back when i did my research (I now forget most of it), I concluded that this (link:
