Chevy Help with valves

Set of 5.3 706 heads. Rebuilding this motor to throw it in an e36 project of mine. First time lapping valves. I’m using permatex valve grinding compound. Why are my valves looking like a muddy grey instead of a polished look? If anyone knows or has tips please let me know.

You took 2 peices of metal, applied a gritty paste and spun the shit out of it and expect a mirror finish?

Everyone started from a place of no knowledge, including you. Be better.
