alright guys can anyone show me a pic of what the gasket that goes beetween the two parts of a 2 peice header look like? im ready to put on my neuspeed n2 and i ordered a gasket set from them. and it included like 4 rings. 2 that feel like aluminum and 2 that feel heavier(also a grayer color) do i just sandwich them beetween??? it almost feels like theres one in grooves on either side of the header already?? im lost sorry i dont have pics to explain but im really lost.
