yes, that will lower overlap , lower lobe separation angles. altering both cams 4deg kept overlap the same but advanced timing in relationship to TDC which also has affect of advance = better low end and retard = better top end . with DOHC being able to do both I would start with intake then move to exhaust as generally intake is more important .(thats why most VCT is done on intake side ) .
