Worse combustion chamber design ever? Saveable?

You can tighten the quench as tight as you can or close to zero...or open it up and rid it completely 'see below' or take some timing out of it. There are important factors to consider on which approach to take.
First place for detonation to play peekaboo is in the quench area, forced and nitrous more. Obviously you approach each differently. So there isn't a one size fits all, and more to consider is the parts package and or 'shortcomings' and 'make dues' to work around/experiment.

Soft chamber vs hard chamber, same head
I know what you're thinking..
Yes thats exactly what it looks like, going backwards... but for fairness and in keeping with "cat skinning".. its up to the builder and only the track/dyno will tell the truth and i for one while i like a good chamber...air flow is king and chambers can get in the way. Balance... is at your discretion.
