He was correct to a point. It's not about one LSA versus another, it's about valve events. IN GENERAL, the valve events for SOME blower combos need a wider LSA to get the exhaust events pushed out a bit and to decrease the overlap a bit, but that's not always the case. Sometimes it'll need more split in duration (or reverse split dare I say), and a tighter LSA to achieve your goals.

ok good, thanks for clearing that up, i figured i could get some insight on here instead of putting something in that might not work to my advantage.
