What allows a Ferrari to rev higher than a 240 (obviously, the workmanship and quality of the parts)....

The fact that they are a 4.6L V12. Small bore, short stroke and the head is designed to do so.
I will turn my rev limiter up to 9k when I get back..
I rev'd to 8k with my stock head. It was fine.
For an SR to rev high you'll need high duration cams, solid lifters, valve springs and a turbo that won't choke out.
My friend with a fully built SR was revving to 9.5k. He would have went higher but that was when the turbo choked out.
