What’s the mod to a Lockheed style servo to stock the brakes hanging on . Something about removing a spring? . Is it worth doing to a new servo before fitting or see how it goes .

Fit and try it first, you may not have to do the following.
Arround the white air valve are 6? Phillips screws. Take off the top plastic filter and body case then there's a piston rod which has two seals, take one off and re-assemble with just one seal.

I have tried the servo 180deg out and as recommended - I could not detect any difference in operation.

Yes mine fits better nose downwards not nose upwards so may go with that and see what happens , maybe it’s to do with bleeding ?

Orientation is solely to facilitate bleeding. The servo will work in any orientation, assuming you can bleed out the air.

I had to do this mod on mine. The brakes were momentarily sticking on, after being pressed, I believe. It was a few years ago, the car had no servo when I bought it.

I had it on my Coupe and found that I could free the servo by a light tap on the brake pedal. It got us home.
