Here is the BB valve cover you are referring to, this one is the HP version with the dripper's, but I have personally seen the non-dripper version at Corvette's at Carlisle a couple years ago, it was a complete A.I.R. CA only smog setup off a 67 427-390 HP with non dripper chrome valve covers.

The only "427" 1967 Corvettes that came from the factory with chrome valve covers were the L88 and L89 engines.

So what you are suggesting is that my valve cover shown in the pic would have been on a HP CA A.I.R 67 Camaro Chevelle being it has the drippers.

My bad. You are correct. It is L89 only that has Chrome valve covers for 1967 Corvettes.
