Accelerator pedal resistance?

I drove my restored ‘64 MK2 for the first time today.
It ran great and what a thrill that was!
My question is:
Is the accelerator pedal typically quite stiff on MK2 cars?
There is no binding, but I find I have to press much harder than I would on my E-type or any other car.
Perhaps the long return spring that came with the car is the wrong one?

Don’t think they are typically stiff , I have added a extra stronger spring to my HS8 carb’s on my MK2 , as the butterflies would not shut 100% , unless I dabbed the accelerator pedal , they snap shut now , with no real diffrence on the pedal !
