Tim, how many miles? How is the car run (i.e. street, racing, combo)? What spark plug are you running ( heat range is more important than the brand. What ignition (and coil)?
Exhaust valves look good. the one intake is a little black and there carbon build up in the combustion chambers that suggest maybe not all the fuel is being burnt well. You only provide two cylinders. What do the other six look like?

Ac plugs ,one step colder than recommended with Trick flow heads .street strip , about 1000 miles on plugs .Pertronix distributor and matched coil .Car runs great for a low compression motor ,12.90 qtr .FI tech six pac setup 13-1 AF ratio ,I can text you some more photos if that helps .The discoloration wipes off fairly easily so I am thinking it’s the 92 octane fuel .The plugs look good, thanks Tim
