If I were interested of combustion, I would have piston with a window and take high speed videos. (And that is what I did)

Are you suggesting the initial head was shaved?My experience for whatever it is worth.
1994 940T, 15g, #46 injectors, MBR, 3" MAF, ebay intercooler, exhaust. Sucked the intake gasket in, decided to do head gasket because why not. Before the intake gasket, it pinged audibly on 91 octane. I prepped a non-shaved head with mild porting and SS grooves. It never pinged again on 91 octane.

Nice. Some torque was definitely gained at low rpm. I wish we knew more about even lower rpm, too.Example of engine stand testing: http://www.revsearch.com/grooves/grooves.html
