Which spring should be used with it . ?

Dependent on the state of tune, From Forges site
Valve Spring color coding
Green - 5-15 PSI
Yellow - 15-23 PSI
Blue - 23-30 PSI
Red - 30 + PSI
I fitted the yellow one on my car and it worked fine on a stage 2 275bhp tune. Probably go with the yellow even on a standard K04 225 car.
