David Vizard, Uncle Tony's garage, Unity motorsport. Mission impossible Dodge 302 Head porting

I disagree with point 4, Vizard writes plenty of books explaining how he does things. Not like he's trying to hide knowledge, not AT ALL. As for porting 302 heads (or any heads), I have no illusions that I can pick up a grinder and match what any decent head porter can do. However, watching someone go through a set of heads and explaining what they're doing at least gives a starting point to anyone who's interested in learning how to port. Or is that supposed to be some secret reserved for some of the head porters who get so bent out of shape when other people post videos explaining how to do it? I'm not talking about UT, he is a hack... but DV is certainly no hack, and I kind of doubt AW is.
its not that its a secret but if one were to actually grind up a set of heads, wouldnt they want a flow benc to see what their grinding was actually doing or if it actually is working? it is common knowledge that most guys screw a set of heads up grinding on them because they dont know what they are doing and the engine runs worse or drinks more gas. In short someone here could watch Vizard all they want without the flow bencha dn the same tools and equipment including the knowledge they wont acheive the same resutls. Vizard went to college to know whet he knows. yeah hes willing to pas some of it on why? it doesnt matter now these engines are 60 year old technology. Vizard graduated college 60 years ago...most here tear their engine down dick areound with a grinder and dremel then tell their brother in law "yeah it has some port work done..." its all bullshit...car runs like the same turd it always was...brother in law in the passenger seat saying "it isnt any faster than last time I was in it...LOL!
