Hey guys,

I'm installing a set of BBK unequal 1 5/8ths in a few hours and was wondering what to use as a gasket sealant?

I have a set of felpro header gaskets and Permatex copper RTV sealant good for 700* it says. Is this a good enough setup?

Any recommendations before I start, any tips or tricks?

Thanks all!

I wouldn't use any sealer. I have BBK's and used the gaskets that came w/ them and have had no problems. Just tighten them down equally and you should be fine.

G/L w/ the install.

It gets so hot at the header I doubt the RTV would even hold up.
Soak the gasket for about 1/2 hour in water before installing them.

LOL I can't sleep. Why soak the gaskets in water?

And that's what I figured about the RTV, probably wouldn't do squat.

How do I avoid leaks?

Soaking them will expand and then when you tighten it down it should seal better.
Also, retighten the headers bolts after a few runs.

never use rtv of exhaust parts

Your RTV may be good up to 700* but exhaust temps in that area could be up to 1100* or higher.

Forgot to mention take some pics for us while your doing installation, and let us know how you made out.

Goodluck

i must say i think the stock gaskets they come with are garbage, i paid 40$ for some aluminum thick ones from autozone and havnt had a leak compared to the 2 i got with other gaskets

if I soak the gaskets won't water get into the heads while I'm tightening them/squeezing the sh*t out of them?
