    Is 1 tube of the 3.35 enough if not how many recommended

    Only a very small amount of sealer is required around each exhaust port. An entire tube of Permatex is more than enough for a complete engine build, where sealer is required at intake manifold gaskets and many other locations. Example:

    If I'm understanding the translation properly, you are asking whether or not to use a composite gasket or silicone gasket maker between the cylinder head and the exhaust headers. DO NOT use a gasket at this location. Only use a ~3.175 mm wide bead (smear) of silicone around each exhaust port opening, let it dry, and then install the headers.

    Si je comprends bien la traduction, vous demandez s'il faut ou non utiliser un joint composite ou un joint silicone entre la culasse et les collecteurs d'échappement. N'utilisez PAS de joint composite à cet endroit. N'utilisez qu'une perle de silicone d'environ 3,175 mm de large (frottis) autour de chaque ouverture de l'orifice d'échappement, laissez-la sécher, puis installez les collecteurs.

    As one of the previous questions says permatex #82180 no longer says “high temperature” it says maximum oil resistance. Although I know head gaskets are very different than exhaust gaskets both are likely to come in contact with unburned gasoline, especially as I tune my new carb and set distributor timing and the instructions specifically warn against contact with gasoline. Permatex recommends #81871 Ultra Copper for exhaust manifolds. The high temperature gasket maker is #81160(red). In the answer to the previous question the administrator says to use ultra copper gasket maker pending “further investigation”. Should I use black, red, or copper???

    Use what you want?! Black works and is recommended. Copper also works. This question has been answered before. Remember, you're not actually creating a gasket. The silicone is merely providing a seal for minor machining variations and thermal expansion/contraction.

    Permatex #82180 ultra black maximum oil resistance says “not recommended for use on head gaskets” in instructions on packaging is this still recommended in place of header gaskets? If not what is??

    The cylinder head gasket and exhaust gasket are two VERY different applications. Please follow the installation instructions provided with the headers.

    Do you use this on your flange to seal headers to heads?

    Correct.
