Re: How important is Quench???
This has a dirrect impact on compression. By what you're telling us, I would suggest that your compression is lower than original set up. This may be a good thing or a bad thing depending on what you want to accomplish.
With the lower compression, you are less likely to get detonation, but I suspect you have lost some overall HP capability in the motor.
I have seen head gaskets with compressed thickness of .015. In fact, that is what I plan to use on my build...but it won't buy you much since the new pitons are .020 lower than originals.
If you are happy with the way the engine is running and perfroming, than you probably don't need to change anything. Other than a marginal loss of potential HP/Torque, I can't see any ill long term effects.
