I've used them but they are old school. I believe in "Percy's Seal For Good" header gaskets. you can buy at Summit. Some will say RTV but if the flange has defects it won't seal. I have reused my Percy's several times and they don't leak or lose bolt torque.

I have yet to find RTV not work if you let the bead dry like the directions say before putting them on the car.

I dont see how anyone could use rtv on a 460 foxbody with longtubes and stock framerails.

I am with Dave De on the Percy's gaskets I had reused my old set a few times with no problems just bought a new set for my new headers I built. I could use RTV now but the way my old headers had to go on and around the old steering column. RTV would not work and after putting the header around the steering column not enough room to get on them.

No need to flip a coin do both just use the rtv on one side to hold them in place while you bolt them in.

Wow such extreme opinions on an exhaust gasket that most have not used. They dont have seal rings and unless you try them you will never know.

Ah.... No you didn't
Percy's seal for good are multilayered aluminum with carbon graphite.
I'd buy em at twice the price. No messing with silicone or time to set.

I think you are right Cletus I am talking about solid copper gaskets not aluminum carbon graphites.....I am so glad he knows what I have and haven't used I just wish he was here to change those SOBs when they didn't work and he could have stuck them where the sun didn't shine....cuz I wadded them up and threw them in the copper scrap bend.

Mine goes in with trans, and headers all attached. I use engine plates for mounts, but if the headers aint on when it goes in, they aren't going on.

Hey Coug,
I didnt deserve that. Is it my fault that you didnt read all the threads on a post. Unlike some I comment on my own experiences. I also race my car not my keyboard.

Dave just because I don't come on here and post everything I do doesn't mean I don't race, I am not here to prove my wanker is bigger, personally I don't care, so I don't post what I do just for you guy to critic..

Copper gaskets
I have a NOS set of Mr Gasket 7165 Copperseal Premium gaskets right here on the wall of my shop, they do have the embossed raised o-ring seal, and are .043 thick. Port opening is 1.25 x 2.08 factory oval style. I had 2 sets of these, I opened one and was going to use them, however the ports of my Sanderson Headers didn't match up to the seal rings so I gave them away, I think to Paul Kane. That's probably the biggest issue is the gasket fitting your heads port, and your header flange. I have Blue Thunder raised Ford exhaust, and with my Sanderson headers I've found that using Fel-Pro's 1419 gasket, and trimming it to my headers works well. I also spray them with copper coat, let them dry a full day, then also use the silicone wet and install. This has sealed excellent on my engine which is supercharged and has pretty high exhaust temps. Summit Racing lists the Mr Gasket copper gaskets at $35 for a pair, not bad if your going to try them, they say stock port, and when matching them to a Fel-Pro 1419 that seems to be the case. Good luck either way.

Copper exhaust flange gaskets are the ONLY one's to use with iron manifolds however, with headers .. probably not.
copper is a conductor

The copper gasket allows the heat building up in the iron manifold to dissipate from the iron manifold through the copper gasket and into the engine's cooling system. Stops the iron manifold from warping, breaking bolts, and leaking. After 2 or 3 warped/broken exhaust manifolds, you catch on.
