Hows the quality of these hedmann hedders, part # 500-68470 82-92 F-Body SBC shorty (3). Has anyone had any prtoblems. Am I gonna have any problems with these hedders since there not the AIR pump ones, and right now all my emmision stuff is hooked up?

 

I am running a set with the 17470 y pipe. They have been on my car for about two years without any problems. I was worried that they may be cheap but at the time I was running short of funds and I needed something to get my car back together. They fit perfect, cleared all my ac stuff and steering and brake lines without bending anything. I did have to modify one ac bracket but it was no big deal. I am also running better gaskets than what came with them and running copper at the collecter. The only complaint I had about them is the paint looked alwful but that didnt last long anyway. I dont know what to tell you about your smog stuff i did away with all mine.
