It's going to be less timing (knock) sensitive with that tight of a quench


Quench Cut - Chamber Softening - Nitrous Friendly Chamber

Creating this shape on the surface of the head changes the way the flame front travels throughout the cylinder by slowing down how fast the flame travels. This allows for a wider tuning window in boosted & nitrous combinations when it comes to timing.



Softening the chamber is going to typically yield more quench volume and a less timing sensitive chamber, correct?

Yes. The tight quench everyone wants for a NA combination will yield a timing sensitive/narrow tuning window in a nitrous or boosted application.
