Does any of you kind folks have a recommendation for a mild cam for a 1978 CB750F that will work with bronze valve guides and stock springs? The engine currently has electronic ignition, cbr600 coils, fresh top end with .50+ pistons, rebuilt head. Mostly looking to build a reliable street engine with a bit more power than it came with from the factory. Any recommendations or experience would be greatly appreciated since i'm a total camshaft newbie
