| + | There are many different types and sizes of header gaskets on the market today. Composite are common, as is fiber types. The composite gaskets seem to hold up a little better, all else being equal, but the main thing is to retighten the header bolts often- like every time the engine is heat cycled- until the fasteners take a set. | ||

| − | + | {{!}}Remember- keeping the bolts tight is very important to keeping the gaskets from burning out. | |
| − | If/when the gaskets take a dump, try a set of the foil backed composite gaskets that come in most rebuild gasket sets | + | For the SBC and any other engine that uses these gaskets as a stock replacement: If/when the gaskets take a dump, try a set of the foil backed composite gaskets that come in most rebuild gasket sets. If they'll fit the head and header ports, they will work as good as most any more expensive composite gasket if the bolts are kept tight. |
Regardless of what gasket that is used, 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 as the foil backed gaskets shown above, for easier installation. | Regardless of what gasket that is used, trim the ID to fit the largest port, be it the header or the head port so there's no overhang into the port.
