Swap pistons for quench?

Probably not for this engine. I started it years ago in my youth with porting the J heads and I’ve never ran it. I’m building the day 2 car I would have done back then if I had the money. I want to experience it like that for a while, now thirty plus years later. This was an original 340 four speed car. I plan to also build a 340 for later if that ever comes. Life is uncertain and I’m not a spring chicken. I have all the parts, intake, exhaust, untouched X heads. Will I go for Trick Flows? Maybe. Roller rockers? Maybe. Got to get this engine in the car for now. BTW; I’m curious about the coating the pistons suggestion. How does that fit in?
