I need new headers

[StevesK10]

Seeking help buying new headers. This is for my 1977K10 400cu.in. Cheyenne. I have been running Doug Thorley Tri-Y long tube headers for 20+/- years. They are now past their useful life. Living in CA the truck still has to pass smog every 2 years. The truck came equipped with the A.I.R. Injection system so the headers need to accommodate the fresh air injection tubes. Hedman is the only mfg. I can find that makes smog legal headers for my truck. Am I missing other options? What experience does anyone have with Hedman. Thank you.

Headman has a good reputation. Being in California modifications are extremely limited. I like the stock manifolds, quiet and you don’t have to end wrench the plugs out.

Playing with hookers today. 10 out of 10!

Removed my 2.5 dual exhaust today. Exhilarating! Mounted the new Hooker manifolds and immediately felt this was one of the best mods I've ever done to a vehicle. These things are bad-a_s_s. 1. No more "special" tools to remove sparkplugs. 2. No more burnt plug boots 3. No more dropping the PS...

I'll never, ever waste time with headers on a street driven vehicle again.
