Don't mess with the cam bearings they look ok

Newbie but what is quench?

Here is a good visual about how quench effects the burn rate and efficiency of the combustion chamber:

You have a roaring bonfire going. In each hand you have a coffee can full of gasoline. To demonstrate how quench effects combustion we take one can full of gas and slowly pour it on the fire. The fire flares up slowly, and only flares up as you pour gas on the fire. This demonstrates a loose quench figure. Too loose and/or in this visuals case, pour too slowly and it never really even flares up, just fizzles.

Now, in the other hand you take that can full of gasoline and you baseball pitch it with all your might at that bonfire. The bonfire explodes with combustion as soon as the can full of gasoline hits it. This is from the gasoline being tossed and tumbled around with oxygen right before combusting which in turn is exposing more surface area and making for more "droplets" of fuel to be burned which causes the fire to flame up very quickly. This demonstrates tight quench where the air/fuel mixture is "squished" together by the quench pad/surface of the piston and cylinder head causing the air/fuel mixture to be tumbled and tossed around exposing more surface area and "droplets" of fuel before the spark plug fires causing the air/fuel mixture to be ignited.

Now that we have this visual, too tight of a quench figure can cause the combustion event to go out of control just like a wildfire when too much wind is present and cause detonation and or total meltdown of your engine internals to happen. Too loose of a quench figure and the fire never even flames up at all. You need to find a balance point for your application whether it be N/A, Nitrous or boost. N/A engines can tolerate more quench because there is no oxidizer present in the combustion chamber/cylinder like there is in a nitrous engine. Heavy nitrous engines need a looser quench figure to become tunable on large volumes of N20. Boost likes to be treated like a N/A motor when it comes to quench as there is no oxidizer chemically and physically speeding up combustion and the flame front, just immense cylinder pressure.

I always urge my N/A customers to run a .040" gasket for added quench in lieu of milling their heads or in conjunction with milling their heads. What's done is done since you already ordered them Nate, but I would of opted for the 63cc chamber and a .040" gasket.

Either way it should run great!
