Is that machining on the head surface intake side something you are playing with or is that just the semi-rough before the head is resurfaced?

That's the "softened" area. It's a 2* "dish" cut into the chamber that effects the quench areas.

Is that something you are doing for nitrous or has it shown other benefits in uses?
It's usually associated with lots of nitrous and higher compression but I think some guys are starting to use it in high boost/big hp apps as well especially with small flat chamber heads with real shallow valve angles.

I know your customer uses a facility that has cylinder pressure data capabilities. Have you tested this mod to see its effect on burn rate?

No, that would mean a before and after. We just don't have time or resources for that kind of testing. Wish we did because I'd like to see that data. On chamber softening, I am 100% just going off what I'm told by others and hoping it works. :-|
Have you guys tested anything like this?
