What are some good hedders?
I know that the SLP hedders are supposedly the best. They are quite expensive though. I was wondering how the other hedders out there were. I have an '83 TA with a V8 350. What hedders would work best with my car? Im not exactly sure, but i was told it is a 350 4 bolt main engine(dont know if that is really any better). I have heard that the Eldebrock TES and the Hooker hedders were good too. What about Heddman headers, and thornly? Which hedders are the best? Which ones are most worth the money you pay? Which ones do you suggest?

You get what you pay for. Pay the big bucks for some stainless headers and they'll last for many years. Buy some mild steel headers, get them coated and they'll last about the same amount of time.
With headers, bigger isn't always better. A typical street engine will work best with some 1 1/2" primary tubes. A lot of modifications and 1 5/8" headers are best. 1 3/4" and larger are designed for race engines and will actually hurt horsepower on the street.
Shorty headers are the easiest fitting. Full length offer more power potential but usually always require modifications to get them to fit.
With that knowledge, buy a set of headers you can afford and install them. Any header is better than factory manifolds.
My best times (below) were with 1 5/8" full length Hedmans.

They're worth the extra cost, especially on a 350 or larger engine.1 3/4" headers work just fine on street cars. But I'd get 1 5/8" for a stock engine.
