I beleive with regard David Vizard, most do not comprehend the techniques and theory he is presenting. UTG following certainly doesn't get any of it. Take the MI 318 build, in my opinion all DV and Charles Servedio have done is, shown the pitfalls of trying to build a 318 into a performance engine. All the hours Servedio put into flow testing 318 heads, I do believe at some point he put a set of 360 J heads just to show the practicality of the 360 heads. I do recall him saying 360 heads were easier to get the flow numbers out of.. I also want to remind everyone that Vizard 318 build was Tonys idea.
