painterman52,
You said you have "cheap" headers so go ahead and wrap them. If they rust out, buy new ones.
A trans cooler was mentioned; think about it, your not more than 8" from that hot trans.
Good ideas already metioned:
Insulation
Heat Shields
Valve off Heater (cheap and easy)
Plug any holes in the firewall and trans tunnel
Get cold air to the motor (whether you live in Texas or Alaska)

header wrap
FYI, I have seen header wrap cause the header tube metal to crystalize and become very brittle. Possibly because they can't radiate heat and they super-heat? Anyways, I have read installation instructions that come with headers stating that the warranty is void if any type of header wrap is used......

Headers do create more heat than the stock cast iron manifolds simply bacause the headers have more surface area that emits the heat within the tubes. Best bet (IMO) is coated headrs and insulate the cabin all possible.
I know that most guys will disagree, but removing a portion of the radiator seal at the sides and/or top allows better air movement through the engine bay. That makes a big difference in underhood temps.

All I have left to do is install the oil dipstick tube and the temp sending unit for my secondary water temp guage.
My feet would cook if I drove for extended periods of time over 65mph. That is why I wrapped the headers. I also took a piece of sheet metal and bent a curve into it and attached it to the topside of the exhaust as it runs under the floor boards to use as heat shields. I'm anxious to get the car down off the jackstands and see what difference all this work did.
And by the way, unhooking and reattaching the headers was not that difficult. Getting them in and out of the engine bay was a total bitch.

I had to remove cluth linkage and bend and twist in all sorts of ways to get the damned things out.
