For a road car, do you need to stress it that hard?
I don't race mine at 1 bar all the time. Yes it will go quicker. But I don't want to be dealing with a bunch of broken bits either. I don't push it to 7k either. Max torque is around 5600, so I gear everything around that. I prefer the quiet life of putting it back in the shed in 1 piece.
Not sure you are gaining much by going into the high rev zone. Pull another gear and sit back and let the torque and those long gears do the job.

plenty of stories of damaged engines on here. I have come to the conclusion these are tough engines. But stray outside the limits and problems will find you.

Good points. I don't ever plan to take it much past 6k rpm again since it's just a road car and not racing it. And the engine has already been out twice in my 11 months of ownership - once to address the myriad of oil leaks and then to address the broken rocker arm/bent valves. So I'm certainly not looking for a third.
I don't have any AFR data yet, but I am bringing it back to my shop at some point soon to address a few remaining items (minor electrical and suspension). My shop has a nice mustang dyno so we can check the vitals including AFRs.
