either way if your changes are not radical it will only shift the inductance, capacitance, and fo a little in one direction or the other depending on which way you need to go with it.
generally you set a target for design and best try to hit the target and tweak to finalize from there.
that is why in these old transistor radios you will find lots of coils on th epcb that are bent in all sorts of odd shapes.
