Well I have ramshorns on my truck and headers on my T bird so I see both sides of the story. It really depends on how you are going to use the truck. If it is a daily driver and you don't need maximum power then the rammies are a more practical solution. They will never rust out and don't need to have a high cost finish to keep them intact. BTW I got mine off e pay for less than $300 so watch for a while and see what comes up. Old ones tend to have rust pits on them though so the new price isn't bad. If you want maximum high speed power from the motor then headers are the best solution. But remember that even in bracket racing you don't need maximum power only consistant power.
As far as resonance is concerned both my truck and the T bird have a low speed resonance that I find annoying. I think that it is a function of the mufflers because I have Dynomax mufflers on both vehicles. Otherwise they sound about the same which is to say pretty good.
I remember reading in some motor test in YBM that the flow of the rammies is about the same as the late model pass car manifolds. This is probably better than some of the really cheap headers but long tube ones may be better than the rammies. In order to get the max benifit for the headers the cam should be selected to match.
I like the rammies on my truck much better than the stock setup with that incredably stupid cross over or the somewhat better solution of two right side pass car ex manifolds. The rammies look right a home and were a big improvement over the stock setup. But for a cruise-in the long tube headers might impress a little more with the know nothing Scrub crowd.
