It's not expensive for vforce
It's a full block totally different design to standard
If you wanna bang 80s technology back in spend 10 quid on some petals lol. You pays your money you takes your choice

Do the inlets need to be opened up to fit them?
Anyone got dyno graphs showing the difference v force reed blocks made by just fitting them and no other parts (other than jetting if required.

IMO unless you lift the inlet window and generally port the inlet track, they are a little spendy for the results your see. They will help in the mid range quite a bit but don't offer a huge amount to the top end figure.

both inlet and outlets have been ported and polished by previous owner
Not really interested in top end but midrange would be good for road use
HMMM whats the piggy bank like
