Amazed how clean cylinder's are!!!

Hello again as you probably know already I am blueprinting my 1969 Chevy sbc 350. Anyway I've gotten the heads off and omg!! the cylinders are amazing. I think that somebody got to that motor before I could have. I also think that I may have found the reason for the detination occuring (I am not 100% sure that that is what it is so any input would be greatly appriciated) could the reason be maybe the intake and or the exhaust valves are just getting too hot????????, I mean that is the only reason I can think of I got 93 octane gas in her, and the timing is correctly set if it's not the valves what could it be . Anyway like I said any input on my situation would be greatly appriciated........
