Hey Phill... You wanted to know what the piston looks like after 3 gallons on a cmr4h plug..
The only issue I had was non plug related lol. I snagged a ring on the intake and broke off a piece of ring as you see the groove in the head and 2 smash spots on the piston. As you see no melting of the piston.
