Steve,
I'm sure you have a great running small block there... But most of us will never know...
This is my problem with guys like you. Everything is a big 'effin secret! You come on here bragging about your "8 second Dart" but you wont even say how many cubic inches it is. For all we know, you have a 600" B1 powered big block under the hood.
You have no problem telling Brett the problems with is port design, yet have no real evidence that what you are using is better/ or even exists! Who does your heads???

Post some pics of your heads up and a COMPLETE rundown of your car/combination and we can see just how good your stuff is.

As far as these small port W8's go, if big power was to be made using small ports, then we'd all be running factory heads... Small port/CSA and high velocity... While these small port heads may work on an odd ball small CI combination or low RPM combination, they surely won't make power with todays average 400+" motors.
