the cam lobe is on its lowest point, the fp arm is completely not touching the cam for at least 1/2" free playing ...

double nut to remove the two fp installation studs installed on the engine manifold ? that could work if they come out ...

can't see them studs base, if they are square welded/pressed inserts, or if they are threaded to the manifold itself ...

the fp is on the way to have a clear view, still on the two studs, barely 1/2" out of the manifold spacer towards the driver side direction ...
