Naw man, all the valves work all the time with VTEC. It's some of the newer I-VTEC engines that start using more valves. VTEC just changes to a more aggressive cam profile at higher rpms.
And as far as I know, the guts of the distributors should be the same. The differences start with the different OBD's.
