WOW! Nice post! I tried to keep it short and sweet but you did a great job on the details and technical end of it. The GM Vortech, Chrysler Hemi, Ford HSC, and the Honda CVCC engines all mix the air and fuel mixture more thoroughly than the conventional combustion chamber design. The hemispherical combustion chamber configuration on each of those engines provides a more uniform, predictable, and thorough burn. So the next time someone asks about your Blazer you can say, "Yeah, it's got a hemi".
And yes, I did notice the switcherooo on the valves. Not too many people know how to tell the difference between intake and exhaust valves, even when they're next to each other.
