My comments are Simple. I think people see things other people talk about and latch onto ONE thing and cherry pick it. It's my opinion that "valve shrouding", while certainly can have an effect, is not a combo killing point, right by itself. That's the point I was trying to make.
Yes, I agree with you. But I cannot see how this design would ever be a good idea. Even if they were directing the intake charge to get more 'swirl', it could have been acomplished just with the shape of the chamber like with so many other heads.
