Sure, just pull your valve covers and you will see the allen-head cap screws that hold down the injectors. Be careful regarding the copper washers under the nozzle holders, they sometimes are stuck in the head spigots. Rotate the injectors slightly after removing their clamps to break loose any carbon build-up. We use a dab of copper anti-seize on re-assembly with some success although Lister does not specify this step.
