7a inlet manifold removal

[iain.atkinson at tesco.net]

Sometime in the near future i need to remove the inlet manifold maniold on my 90 so that i can replace the rocker cover gasket and probably the lifters and cam chain whilst i am in there. Does anyone know if the injectors need to be removed as well or can they just sit in the manifold. If they need to be removed how is this done?? I am familiar with injector removal on the 10v cars is it similar??

TIA
