Suggest some headers for me please...

I've got a '79 L82
No A.I.R. pump, no EFE valve, has AC
I want to dump the manifolds and put on some headers.

I don't know anything about headers other than I've head that you can get better horse power from using them. I do know that the wrong headers can cause problems if the ports don't line up. I know most are not street legal. I'd like to get some street legal ones if I can. Is this possible?

The exhaust head ports are 1 3/8" square (with the corners rounded).

Any suggestions?

Edelbrock's new TiTec (titanium finish over stainless tubing) headers don't chip, peel or rust and are smog legal in all 50 states for maybe $350.

First problem is headers leak, making rude noises. It takes special locking fasteners at the head and double-nutting or safety-wiring at the collectors to keep 'em tight. Save yourself some trouble, pay a pro (like a race shop) with plenty of experience to do this.

Second consideration is headers will not give you much more performance or mileage when run through a catalytic converter and muffler(s).

But they look and sound cool, so maybe you feel like you're going faster!
