aright, you spend the money to put half a point more compression in a B17, and you'll be just that much cooler. "can you hear that half a point more compression? it really made the car sooo much faster." Just put a bigger fart can on it, it'll at least sound faster.

I'm saying for a street car...intake, egg sauce, header...don't even bother, it doesn't even matter. If your building a race gas autox or drag car and your changing to big cams, even bigger ports, huge headers, & an enormous coffee can out back, then you definitely should bump compression.
