Wow... I had a totally different experience with ram horns.
After replacing my intake and carb with a higher flowing design, I started over heating like crazy. The faster I went, the hotter my truck got.
I replaced the radiator, heater core, hoses, water pump, thermostat, and even bypassed the heater core, all to no change in the problem.
Finally, I pulled the ram horns off and put long tube hooker headers on, and it ran cool from then on.
The best way I can describe it was that the ram horns were causing a restriction that was causing the truck to run hot the higher the rpms got. After removing the restriction, I had no problem.

I haven't had any problems with my headers (until I got heads with freaking angled spark plugs, but that's a problem of my own creation), but maybe it's because I didn't by cheap ass flowtechs or whatever. I've learned that you get what you pay for.
