Headers vs. Manifolds

Maybe, I've never tried it. I have seen guys use C body HP manifolds and angle mill them. Not exactly an easy solution but I've heard that it works. On my Duster I just used the smallest header I could find and that seemed to work okay but it was only 600 hp.
I weighed everyone's advice and thought about the power I'd lose and decided to buy some B-Body headers and do the minimum necessary clearancing. Much as I'd like to buy some TTI's, it's just not going to happen. That being said, any specific brands or P/Ns to buy or avoid?
