I can't speak for Ca. emissions vehicles but, I owned/bought new a K30 in 77,79, and 80. All 3 had the 400sb and Turbo 400 and dual exhaust. These trucks were rated for LEAD Premium fuel. None had an egr or cat. The 79 & 80 had the air pump with only a single hose/pipe on one side for recirculation system.
