Well given we are agreed 100% that I will be either right or wrong, I'm going to be thinking about contingency/taking advantage of the situation.

Ryephile: You mentioned in another thread about Burns' X-design software. I'm familiar with Burns products, but not their software. The question I have is, since a lot of their customers are high-end race teams, do A) they use continuously variable cams in these cars (some I know don't like the C5-R/C6.R and NASCAR, but the ALMS cars I don't know) and B) does the software take that into account.

Reason being is that we can now muck around with overlap on the fly, and that can be used to tune-out reversion flat spots.

Extension question. I've heard that stepped headers help maintain low-end while boosting top-end. I've heard two theories why. One is that the steps sort of replicate a cone and it is better from an inertial velocity/pressure point of view. The other is that the steps act as reversion barriers to pressure waves. Any insight?
