By now you may have guessed, I occasionally step "out side the box".Cheers automotivebreat(h)...lol. I thought you were angled slightly off point of igniton, now i'm begining to understanding why.
Yes more grooves provide more of the same benefit.Whats heads are you showing us?
They have bloodly big squish band, I can see these heads will benefit loads with grooves.
The opposite is true, detonation threshold is raised.Do you not have to worry about possible 'hot spots', which may lead to det in a turbo engine?

This is my results.
I'm able to use the same boost pressure on regular, as i had with premium petrol before.
220 kpa with the same timing.
Before 28 Mpg Imp. Best.
After 32 Mpg Imp and i'm still tuning.
AFR before at cruise 16-1
After at cruise 17.5-1 and nothing strange drivability problems.
I'm going to try 18-1 next week if i can burn it.
So far i'm Happy.
If I were modifying this engine, I would groove the cylinder heads to direct squish flowC20LET chambers:

looking at one of the last few pics, you have one where you have three grooves, going towards the valve....it looks aloost like your on the seat? couldnt that cause potential seat failure, after a certain time?
i may be wrong on this!!lmao
Unfortunately we don’t have the resources needed to “see” what’s happening inside the activeInteresting!
But i suppose to find out the optimum, without trial and error you need to see where the current squish is happening, so you can 100% find the best angle for your grooves.
