The Arctic Cooling Freezer 7 Pro Rev 2 will be more than fine for a stock i5-2400. At £19.39 it's by far the best sub £30 heatsink.
Though I'd point out it seems a little mad selecting an i5-2400 and a P67 Chipset. For £19 more you'd be able to get an i5-2500K and actually be able to use the overclocking ability of the mobo.
Yes you would have to spend another £19.39 at least, for the heatsink.
So yeah, I'd suggest save up an extra £40
