Hi,
I will be doing a head gasket change with a mate but I need to find out what parts etc.. are needed to complete the job ! obviousley I will need a new Headgasket, head bolts etc.. but what else will I need ? I've never done a headgasket change before

, my mate has though so the technical knowledge is there ! Car is a series 2 erst (1988) if thats makes any difference
any help greatly appreciated
Duncan
