318 engine differences between CA and 49 state versions

As a California resident it seems like we often get the dumbed down, castrated version of whatever the rest of the country gets in terms of performance. I understand this fully kicked in in the mid 70s, but were there differences in the 67-69 iteration of the LA? PCV configuration, heads, exhaust manifolds? My Chrysler catalog does not give the state by state variations of cars at any point in time so I'm wondering if I'm being cheated of any power :)
