What is Quench
I feel responsible for starting this mess but it's a good conversation. After reading through this thread I still don't know whether I could explain "quench" but I tend to think along the lines of common sense and not about all those formulas and mathematics. I think a closed chamber is pretty efficient especially as long as the piston isn't a foot below the deck at tdc. Keep the compression reasonable (9-9.5/1) and rock. When I had my heads done at Radar's shop, Woody polished the chambers, port marched and opened the ports and shaved them to minimum cc according to the book specs. (63cc if I remember correctly) I ended up with 9.68....static ratio and have no issues with detonation. I liked what he did and it works.
