SLP makes the best headers in my opinion, but they're also the most expensive. Check the GP board, there's a special right now.

I used a set of MAC headers and they worked great. The emission tubes still hook up and I did not have any exhaust leaks.

SLP's are pretty pricey if you buy them new, I'd suggest finding a set of used ones also. But if you cant, dont be afraid to go with Edelbrock. They work fairly well with a 305, the SLP's 1 5/8 collecters are a bit much for a 305. So if you have a 350, go with the SLPs, and go with some coated Edelbrocks if you have a 305...just my .02
