Fiat 127 / A112

Hi!

I'm assembling my Abarth spec engine, and the valve springs on my cilinderhead are painted red and white(or is it yellow? can't really tell from the oil contamination on the paint)
can anyone tell me what this colour code means?

i've been told that there were also blue/white springs, does it have to do with spring rate?

thanks guys

i'm getting very close to having the engine closed... i've stumbled on something... crank scrapers, on what i've read... they are a nice addon, but... are they necessary? is anyone running them? are they available for the 903? or do i have to make my own?
