all are very expensive and IMHO not worth it for the average racer or bracket car


I agree completely. These are only for max effort, cost is no object efforts like Prostock, Comp eliminator, and SS/AH. But a few of these sites do have some interesting info on the subject of headers and collectors.

In theory, there is no difference between theory and practice. In practice, there is.
