you can just whack em on and check the clearances i think. I had a cracking set of Keith Dodds somewhere but i'll be chuffed if i can find them!!!

fit rockers set tapets and push car in 4th and watch the valve springs
if the coils touch then you need different springs
to fit the rockers properly you need to change the head gasket (some times you get lucky and don't) so while the head is off you could buy the right springs any way
a good mini parts supplier should be able to sell you rockers and matching springs
