I have the BBK pulleys on my 97gt, they come with a new alt. pulley. That way the alt doesnt spin slower. Your heat will work fine, it has nothen to do with pulleys, and the A/C only does that at idle, above idle and you'll never know the difference. I also have a 160 stat and the computer is reprogrammed to turn the fan on a 170, and have never had an overheating problem... and just to make a point, i live in Phoenix Az where its get into the 110s on a daily basis.
