Slant 6 Turbo 68Dart Project

My experience with turbos is alot in diesel applications but not so much in gas and none in slant 6 I was just figuring if u have a valve that opens farther and stays open longer will help with the lack of flow from the head design I understand that lobe separation needs to be alot due to the air wanting to take the path of least resistance which would be out of the partially open exhaust valve. What I was wondering is if I can get a cam ground that will open the valves a little farther and longer I could squeeze more air into the hole and along with air comes the fuel and a bigger bang. But mostly am I just shooting myself in the food going to a 4 barrel intake to have a boosted slant with good road manners and reliability?

Also serj are you making the racks for trunks kinda like the challengers use to have for luggage racks?
