There's no denying it opens the valves a little sooner, but you're not talking about a magical 50HP difference. Who's to say on some combos you might lose power? IMO it's a lot more important to get the geometry on what you HAVE correct first.I cant argue cause I don’t really understand it all but it’s in the geometry of the pushrods of the 1:6 that benefit more so than the 1:5 rockers. I’ll have to go read Mikes articles 4 more times. Maybe my thick skull will understand it better then. Lol
