Keeping the bolts tight is the major thing.

If/when the gaskets take another dump, try a set of the foil backed composite gaskets that come in most rebuild gasket sets, if they'll fit your ports- they will work as good as most any more expensive composite gasket if the bolts are kept tight.

Regardless of what gasket you use, trim the ID to fit the largest port, be it the header or the head port so there's no overhang into the port. After trimming, start all the bolts and just drop the gaskets into place. Other header gaskets can have the bolt holes slotted in the same way for easier installation.
