I concur. I’d skip the Hooker Super Comps and go with regular Hooker Comps. They’re cheaper, slightly thicker wall tubing for street use and you can practically throw them at the car and they’ll land in place. Let me add the fact that I’ve installed Hookers on MANY cars and have NEVER had to take the BFH out of the toolbox.

X2.Hookers suck.Way too low.

They're stainless steel, very nicely welded and even come with a high tech hourglass style merge collector (something Chevy actually came up with in the "we're not racing era"....L-O-L) . Available in 1-7/8-inch or 2.0-inch. Not cheap, but probably the highest quality production line headers I've ever worked with.

Those are sweet, but I don't want to spend that much dough!

Anyone have any luck with Doug's? I have found the tube size and collector size that I want. 1 7/8", 3.5". They have also come recommended by a few guys local.
Thanks for all the replies and help

Dougs hang low. I have the American racing ones on my car now and they are worth every penny. Let me know if you want pics.

I like the hooker 2455 this header does not hang low like a super comp does and is available in carbon steel and stainless , I currently have the stainless on my 2nd gen camaro and my chevelle they fit very well and must work good the chevelle has been 5.98 in the 1/8 at 3500lbs on engine alone. Spark plug access is very good , I've also used the steel version on wife's former daily driver 1970 elcamino with no gasket issues

What diameter tube are you running and what size collector?

Great race headers but to low for the street.Lemons are killer but so is the price.

The hooker 2455 is 2" primary with 3.5 collector

Is it difficult to get to the plugs with 2” primary?

Will the reverse lock out work with headers?
