I'm still having trouble trying to figure out how all these CA vettes are using the long tube headers with AIR system and passing emissions.
1. What did you do with the preheat stove pipe that comes from the bottom of the Air Cleaner housing that goes into the stock header?
2. How did you install the EFE actuator to the heat riser for smog on the long tube headers? Did you just get a 3" version for the end of the long tube headers and fabricate an extension for the EFE/heat actuator valve?

2. The 68301 kit comes with an adapter that you would add just past the reducer. You would then have to run a long vacuum hose to the actuator valve.
