What is the absolute maximum revs our unmodified, factory head and valve train can handle without floating/damage (given a built bottom end, like the SP63 in your engine bay)? [dunno]

Not fully sure.

My old DHM tune back in the day revved to 7,500RPM, but I never tracked the car with that tune.

Had the limit set at 7,000RPM for the last few years and it hasn't been an issue on track (and apparently my factory engine is fine).

I can ask SP63, but when I floated the idea of 7,500RPM they didn't bring it up as an issue.
