I don't have the money to go that way with my builds! The other trick with that TK L20 head was moving it across on the block to unshroud the valves in the bore. It was for a Sport Sedan running about 14:1 and e85 (basically alcohol). But yes, his 120bhp/l is an absolute top effort for a NA 2v full race motor!
I don't really understand what your asking - I assume "wonder if these chambers work just as well for better boost numbers than H89 chambers" means for turbo engines? Anytime you improve flow, it's obviously going to help, but if TK's customer was running a turbo engine, I doubt they'd have bothered going to these lengths to extract every last bit of flow out of the head. It's just not as important in turbo applications.
