Been stripping down my old head today to put the manifolds and fuel rail onto the new head but am having abit of confusion with my head set.
To start with, the inlet manifold gasket that came off is the one in the top of this picture, my head set contained the 2 below, 1 is thin metal, the other is a composite material. Which one do i use? or do i use both? its not quite the same shape either but will fit if i loosen the fuel rail.

The head set also came with a bag of smaller seals, 4 black rubber rings which i assume are the injector seals but they seam abit big and 5 copper washers which i have no idea what they do!
New injector seal in the middle, old one on the left, copper washer on the right!

The head set is made by a company called BGA and the part number corresmonds to PB engine code. Any ideas what the copper washers do? and whether those injector and inlet manifold gaskets will be ok?
many thanks in advance!
