Yeah OK, Keep beleiving half that crap. I guess engine builders like Joe Sherman, Bill Jenkins and Warren Johnson have it all wrong as well.
If you beleive that an totally unrestricted exhaust will out perform a slighty restricted one they why does an exhaust port flow better from .100-.600 lift with a 10 inch header pipe bolted to it than with nothing at all? Don't beleive it? chuck up an Edelbrock performer head on your flow bench and try it open, then with a 1-5/8 header tube, 1-3/4. That exhaust port will flow better with the 1-5/8 than anything else. It's the same reason that some heads flow better without some material removed when the obvious and logical thing would have been to remove the restriction. Chevy had a head W port that had a large bump (or Vane) in the exhaust ports we removed them in serch of more flow. We had to go back and weld the bumps back into the head to increase the flow. It goes to show that everything isnt as cut and dry as you would lead people to beleive.
Did you realize that exhaust movement can stall in an exhaust that has too large and create turbulance that can restrict flow over a properly sized exhaust? You have to keep the exhaust flow moving at maximum speed without stalling the air.
I don't ask people to beleive what I tell them but I do give them my proven opinion. No matter wheather you approve it or not my advice is proven over years of many many cars. You seem to be stuck on two or three cars and years of pratice tuning those few cars. I really do beleive you are a smart guy and I beleive as an auto technician you are prob very good. When it comes to airflow dynamics youre are a hack.
This conversation is over with you.
