I've used a few different brands/styles of headers over the years. In the old days Hooker super comps were the "go to header mainly because they had big primary tubes but always required some modification to get to fit. I've tried the shorty headers to never found any to work well without beating on at least one tube. I recently tried a set of Schumacher tri-Y headers on my BB Challenger and I was very impressed with the fit. I have TTI on my SB Cuda and they fit awesome, but are not cheap.
It all depends on what you are trying to get out of them, if this is a performance build then you will want decent header, but if it just for a "little extra" then you could probably use whatever, but you could argue why not just use manifolds then.
I will say this, whatever you decide to use (other than manifolds) I highly recommend getting coated headers. I am not sure where you live but if its anything like the Pacific NW, painted headers will rust within 6 months.
