1976 EFE actuator to modified Headers
I am installing the hedman hedders #68301 because they have the AIR tube inlet for the smog system. My question is does the EFE actuator connect to the heat riser in the stock exhaust? My AIM book does not show how this is connected? If it does I'll need some sort of extension to connect to the long tube 3" collector I assume?

Thanks. I was trying to determine if the EFE just went straight into the riser which is apparently does, but no in my build.

I FOUND THE ANSWER:
Just talked to Hedman, and their EO certified exhausts come with the heat riser adapter for the long tube header for stock heat riser and a separate hose and adapter for the heat stove.
ALL'S GOOD!!!
Thanks again

You originally stated you wanted Hedman 68301. In the link below it states they are NOT legal for California. So what headers are you referring to that are EO certified.

I noticed that on Jegs as well and was concerned, but called Hedman previously to ask. The 68301 has and EO sticker as well as 68307/67308 (for non AIR) and are legal for sale in California. Some forum members have installed and passed emissions in CA previously with that sticker.
Thanks for pointing that out.

They are legal for 75-80 MY Corvettes. Unfortunately, they just dumped everything in the subnotes straight into the description blob.

-27 is the latest one, which specifies for 350cid engines only.
