That gap does look huge: I've just slung a 700c with a 25mm tyre in 27" forks and the gap twixt tyre and crown is 30mm.
Measure from the brake mounting hole in the forks to the rim: I have a pair of exceptionally deep drop brakes in the parts bin.
You may be interested in threadless forks, but the steerer in your Raleigh will be 1" whereas the standard for threadless in 1 1/8".
There are threadless 1" forks but they are scarce and pricey; you'll also need a new headset: far more money than the frame deserves.
