Anyone flowbench the trickflow 190 heads yet???

You wanna hear something? I've flow tested many cylinder heads on my bench which is about 40 feet from my dyno cell. I've tested many engines with the very heads that have been tested on aforementioned bench. I've seen dyno results that lead me to believe the cylinder heads were underperformers in relation to the observed flow numbers/curve (oops theres a hint) . I've seen dyno results that far exceeded what the flow numbers would indicate. I've also seen many dyno results that I thought were bang on. Now I am getting a pretty good handle on all of this but until I can establish a trend the flow numbers of a head don't really tell much at all other than maybe potential, maybe. J.Rob
