hey guys got some more question. i just took the heads of my motor and i noticed a couple of my exhaust valves are white, what would cause this, and is this bad? also what should the top of the pistons look like?mine look kind of a charred black color and seems to be some stuff flaking off them kinda like a cripsy sooty chip or flake not metal or anything.

 

Those sound like fairly normal combustion chamber deposits.

 

All normal

The ones with white exh valves are a bit leaner than the others

 

oh ok as long as everything sounds normal then im happy how would you go about making those other sections richer or is that basically something to live with.
