I myself have always had good luck with headers. I have had the same headers on my sons Dart since we put it on the road in 1997 and it has never had a leak and they still look good. The same goes for my 63 but its only been on the road for almost 2 years.
But like was said it just depends on what you want. I like headers because I have to build cheap combo's and I need the hp headers gives me. But if someone can get the 500 hp or whatever they wany with manifolds then they wont need headers if they are happy without them.
I was thinking about getting the Max Wedge manifolds as to me they look like they might flow as well as headers. But they cost way more then my Headman's and the cast iron manifolds are much heavier. And any drag racer knows weight slows you down. Ron

I sold my set of rusty pitted manifolds on eBay to some guy in Sweden for obscene money IMO, but he just had to have them. Then I bought a set of the repro manifolds for my 440 Cuda from Year One. They fit perfect and look brand new. The only difference I could find was a "Y1" cast in the back side and you can't see it when mounted. They have other castings for that original too. I have had them on for about 2 1/2 years now and they are just beginning to surface rust, so I pulling tham at the end of the show season and will have them ceramic coated cast iron grey for about $150. I could do a permanent coating myself, but for that money, why?! I am sure you would like them as much as I do, and I believe there is a Year One code floating around that is good for 20% off, which would bring the price down below $300. I know I could have bought used somewhere, but I like the fact that 1)new 2)no pits 3)no cracks 4)no looking through swap meets, and 5) comes with all the hardware, etc. I did remove the heat riser and sold that on eBay too! What a country! See the pic.

for me its defenetly clear, i want much HP and no Headers, because i like the understatement!!!

But if my car is slow machine after that.... hmmmm, i maybe dont like it! i thin it should go up something in between 11 and 12's with slicks...

what kind of setup you would run?

It's always been my theory if you're running a full exhaust, by the time it gets all the way down the head pipes, through the mufflers, over the axle and out the tailpipes it doesn't know whether you had headers or not.

Race car with open or no exhaust system, I'm sure headers are worth some hp, and have the scavenging effect to boot. I still hate to look under the hood of a nice mopar and see a bunch of crappy aftermarket parts.

The low deck 470 in my B body car was a fairly inexpensive motor to build. Unported Edelbrock heads, Performer RPM intake, Eddy 800 cfm carb, Mopar Perf .528 solid cam, etc.

475 to wheels...nice. How does this cam compare to the one in my sig below. Sounds like the solid is at least as tame...but seems like it would make more HP.
