I'm a little confused here, Are you wanting to repair the old head or do you need the stuff for the Endrigo? measuring the studs in the old head will give you the size. The gasket depends on the type of exhaust pipe mounting flange. If the flange is welded to the end of the pipe then you'll need the flat gasket. if the flange is loose and can spin on the pipe then you'll use the ring type that looks like a washer. The endrigo head should come ready with studs. probably 8mm. Most of the large port heads, 30mm, use 8mm studs. Call your vender to confirm this.
