What kind of HP are you making? I have a 67 Firebird with a 72 400 that was taken up to a 461 using worked Edelbrock heads and is pushing about 560hp. It also has a 5 speed and 3.73s. My builder used a QUICK FUEL 850 BRAWLER with Edelbrock Victor intake but that was too much intake and after talking to Butler I switched it out with a Performer RPM. It runs a lot better on the streets now. I'm also running Doug's headers and a flowmaster exhaust.

The car has never been on a dyno. I've had it since I was a teen and when I started making adult money I had a friend of a friend with a machine shop do the engine work. He is a great machinist but terrible at finish work so I kind of ended up with a basket case.

How do you like the Doug's headers? I've got a bad leak on one of my manifold gaskets so i'm planning to buy some new headers but want to be able to justify if the price is worth it over a set of ceramic coated long tubes from summit.

No matter what headers you buy/use get a set of Remflex gaskets, best out there and help seal any minor imperfections in the cylinder head.

I'm really happy with them. I was running Hooker Super Comps in 1 3\4" but with the new engine my builder was pretty adamant about me using 2". Doug's were closest at 1 7/8" and came in round port which I need for the Edelbrock heads I have now. Both fit great. I would compare metal thickness and fit before buying a set.
It looks like Hooker is now making the ceramic coated super comps without a collector flange. You would have to go with regular competition series if you want bolt together flanges.
