1931 model a engine

[1931FB]

Good afternoon
Relatively new to Model A, but I recently removed the head off my 31 Model A coupe. I’m not really sure what I’m looking at as far as valve colors. Carbon buildup on pistons I have enclosed a photograph and was searching for some opinions as to what people may think.
Is the engine running incorrectly or correctly according to colors? Is it running poorly according to colors anyone ever take a head off see what the engine looks like open for suggestions.
Thanks all
