Manifold Heat......

Most of you guys know that I have a 6.1 intake on my 5.7 and use my own custom cnc'd spacers/adapters to clear the truck timing cover (was too lazy to mill the timing cover at the time). The spacers are 1.5 inches tall and work just great. Here's the problem....after driving and I pop the hood, the intake manifold is FLIPPIN' HOT, not just kinda hot, but hot enough to burn you hand if you left it on there. I got some phenolic material and will make some spacers/adapters to go between the intake and my aluminum spacers/adapters. Does anyone else have this problem with their 6.1? I'm open to all advise/constructive criticisim. By the way, damn thing runs like a scalded cat on a hot tin roof.
