I have a header bolt that won't seal. What have you had the best luck with?

Dab of Ultra Copper/Orange Permatex RTV hasn't let me down yet. Assuming coolant is leaking.

1.use as many ex mani studs as you can... 2. If you can't use the long header bolts and use a dab of sealer or teflon tape and you should be G2G...

As stated above, and I've also used anti-sieze with no problems on aluminum race heads. I use anti-sieze on all exhaust fasteners anyway, as well as on anything exposed to coolant, and on wheel stud threads.

I have used this Permatex Aviation Form-A-Gasket before without problems but one bolt is leaking this time. I'll give the copper rtv a try.
Thanks!
