The 1963 Ford Indy engine had the "bundle of snakes" exhaust system on the top with pipes crossing over to have 4 equally spaced exhaust charges in each exhaust header, some race car headers had pipes crossing under the trans to get equal charging in each header. This system is called a 180 degree exhaust. It has some advantages in racing situations, but for the most part it's a very difficult and costly system to manufacture, package and install/service in a production vehicle. | The 1963 Ford Indy engine had the "bundle of snakes" exhaust system on the top with pipes crossing over to have 4 equally spaced exhaust charges in each exhaust header, some race car headers had pipes crossing under the trans to get equal charging in each header.

| + | Keeping the bolts tight is the major thing. | ||
| + | |||
| + | 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 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. | ||
