Put the springs in now. If you don't, the valve bounce will weaken the head of the Inlet valve as it bangs against the collet and you will drop a valve.

I learned this the hard way, first time I bought a new engine as the standard springs are only designed for 3000rpm.

Note, if you had a Japenese engine or collet the damage to the valve could alraedy have been done and I would suggest changing the valve. But the radius of the Thailand collet is softer on the valve and you will be okay.
