You are talking $ 120 to $ 1000 dollars. Most of us are geared to dollars.
"Bad headers are better than cast iron."
Stepped tubes are good.
Flow cones are good.
Tri-Ys are good.
4 into 2 into 1 are best, in my opinion.
Shorties are good.
I'd go for stepped tubes.
I'd stay as small diameter tube and collector as feesible for street driving.
I'd go for ceramic coated for longevity.
Look for 3/8 thick flanges.
Heavy gauge pipe.
Don't forget header extensions of 14-18" length before necking down.
As a generalization I would say Hooker Super Comps designed for your vehicle are the across the board winners..... maybe not the best in every application,,,,,, but the across the board winners, if you need a blanket endorsement.
There are several good manufacturers.
If I had lots of money, I would go for 4-2-1 and ceramic coated

.
We used 4-2-1 with the ancient 1960 long ram dual quads on a 440 Magnum with a 292/509 purple shaft and it wound past 6000 just as fast as it did 3000. Everybody that saw run it had eyes bugging out of their heads that looked like coffee cups. :thumbup:
Too much BS about long rams that won't pull past 5000 rpm..... :nono:
Also, fabricating a bracket from the collector to the trans to support the weight and pendelum action of the headers goes a long way to preventing blown gaskets and warped flanges.
