I have found a spring on ebay that works for valve spring.
Ebay... 0.6mm Wire Diameter 304 Stainless Steel Compression Spring Pressure Small Spring.
I ordered; Wire DiaODLength: 0.61220mm.
They fit and the spring pressure closes the valve. I have not finnshed assembling yet but I don't see any problems using these springs.
