No need to yell.....You ever hear of the PM function??? I have 3 different thicknesses listed in that one post....which one are you talking about?
With the thinner ones, I think there are noticable gains over the stock thickness....but I don't have any dyno numbers. Many others have used these thinner gaskets.... maybe one of them will have concrete numbers. Cometic can tell you how much it will change, but I think the figure is about .3-.5....maybe a little more....
If you need a set, lemme know....I have one set of .027" left. Check with Crash477 first though, he wasn't going to need his anymore.
