header tube size

Strangely, mine doesn't appear to like step headers. Been running them (1 3/4" to 1 7/8") since last year, but I have never even had the thing on a dyno until recently. Bought them on the recomendation of someone I really respect. The step headers only appear to help down around 5000 RPM. Past that straight 1 7/8" picked it up everywhere. If I were foot braking they might be worth more. Wonder what I'm doing wrong, that it doesn't appear to like them, when everybody else runs them?

Thinking about trying a set of 2" primaries? My old, original-1975-rules-292" C/SM Camaro loved 2" headers. But, it was a stick car leaving over 8000. This is a 358" LT1 trans brake car, the converter hits about 6000.
