When Headers Don't Matter

Steve Dulcich has posed the theory that headers don't matter nearly as much when paired with a small cam as they do with a larger cam. To find out, the guys look at the percentage of power gained on our Ultimate Average 383 when using factory-style manifolds, shorty headers, and full-length headers with a tiny 200/206 cam, and then again with a meatier 230/236 stick. Does a smaller cam benefit less from a header upgrade?
