I don't want to sound rude, trust me, but that topic has some long threads on it. Do a search in the archives, and make your own judgement. Some people have said they never noticed a difference, and others have said it's a noticable difference.
If the temps. in your area do get higher than about 85F, and/or you run headers, you'll want to run some type of insulator spacer between the carb and manifold. I had a problem with vapor lock on a long trip one time. I'm running headers, it was very hot, and I didn't use a spacer. I hope this helps. John
