Well the other night I was showing a honda civic whats what, and i step on it in 2nd at about 35 mph, about half a second later i hear CRACK and then click click click click click click....Turns out A piece of my gasket blew apart so it was flapping around in the header making the click sound. The dealerships performance guy is putting a new gasket in from kooks tom but I wanted to know if this happened to anyone else

Mine has clicked since the first day I put them on, and it drives me nuts (short trip

). Were these the carbon gaskets included with the headers, or did you use different ones?

yea they were the ones included with the car, this click was def the sound of something hitting metal tho and it was louder than my exhaust/kooks/procharger combined so after a day I couldnt take it anymore

When I got the Kooks Headers The Flange that attaches to the head was about .04" out of flat. When I contacted Kooks they said that was in spec and don't bother me (Added the last part but that was the way they treated me).

When I received the B&B headers the flange was straight and the gaskets I used smashed nicely and I have not had this problem.

I would check to make sure the header flange is flat and if it is then switch to the re-usabe Aluminum gasket (The one on the Faq) and you shouldn't have this problem anymore. If not flat then get it to a machine shop to get it at least within .02".

hahahaha im not the one who referred to him as a "poor soul"

im not gonna lie tho the thing was fast as hell, they say those carbon fiber floor mats and wings add 70 rwhp to the brain

George at Kooks assured me that their stock gaskets and studs would work just fine.

So far, he's been right!

BTW, my penis has received many compliments through the years. I must admit, darn thing hasn't always been too smart, though.

Had the same thing happen. Mechanic at speed shop said they have had problems with Kooks gaskets and replaced mine with OEM set he said they were better quality.

I used the stock gaskets, the metal ones that were with the manifolds that were stock, I ahve never had a problem, my experience with after market header gaskets are not good.

Aren't you the one that had troubles with the dipstick?

Any of you kooks guys have stock exhaust manifolds you don't need anymore?

I want to take a shot at seeing if my car can pass emissions testing.

Does anyone know if they make the copper header gaskets for the LS6-LS2?

I've used them in the past on different motors and found them to be a good solution when I keep blowing the fiber gaskets.

I'll add that they are a one shot deal. They have a crush seal and if you install them and they leak you're SOL. Kind of expensive.

I used the Percy's Seal4Good dead-soft aluminum exhaust manifold/header gaskets were used, part number 66032.

They work well and can probably even compensate for the poor flatness on the Kooks Headers. I may bad mouth the headers but they are designed well and I'm sure they flow better then mine. I was just dissapointed with the quality control so what this means is they required more work to get them installed properly. If I were to keep the set I had I would have surfaced the flange and flanged the collector end.

These gaskets worked well for me but I torqued them twice. Once when installed then again after about 5 heat cycles.
