Edited again for bad math....have to get back to you guys after the flooding is over....AF has me running ragged
Bottom line though, the quench discussion should really be a movement discussion not a number discussion. It is true that a good chamber does not need as tight of a quench because you generally have a better and more purposeful churn, especially if the chamber has some sort of pad on both sides of the bore to move the mixture around. However, even though you can find a smidge of torque from tight quench, especially with a piston that matches your chamber, the more your fuel changes (pump gas versus a more stable mix of race gas) the more you want to have movement toward the location you want your burn. A street engine is not a race engine, and you never know what is coming out of the pump nowadays, so having the right quench pad design for the head and a logical distance does matter. It's not just tight versus loose, it's a decent distance and close in the right places
In your case, There is no choice that will be bad. The quench distance at .062 at max of "good" and there the compression is a bit lower, if you get it to min distance, you do have a little more compression and power, single digits of power and it will still be good. The chamber has a good shape, and a flat top piston has quench pad pretty much wherever it's needed for the head
