I *think* SR changes 'Flesh to Stone' to that perma-hold effect (to stop items being lost etc.). I don't recall it changing the 2nd-level 'Protection from Petrification' though... have you looked for it at High Hedge?
I don't know what mod changes which green scroll to 'Protection from Polymorph' but assuming it protects against the whole school of magic, it sounds like the basilisk innate ability just needs to be patched to be in the school of petrification/polymorph... you can do this pretty easily in Near Infinity...
From what I'm seeing in my various installs and the source codes / documentations, I'm like 90% certain removing Spell Rev's main component will restore actual petrification - I think, but won't know for certain for another couple hours, that the Spell Rev petrification thing triggers when *anything* tries to petrify you, or at least that's how it looks. Like it checks if you should be getting petrified, and if so, hits you with something that slows you on failed Death save, then turns you gray and Holds you on the next round if you fail the Poly save. So what ends up getting called isn't the Petrification debuff, but a pair of separate ones that bypass normal Alteration protections. Assuming I've pinpointed the issue, this *really* needs to be separated from the main component of Spell Rev, and then fully documented.
CONFIRMED via multiple installs and testing. Spell Revisions main component has a bundled in edit to how Petrification works, causing all forms of defence against default Petrification to fail EXCEPT for Familiar's petrification immunity, making Basilisks impossible to deal with effectively.
WORTH NOTING: If you use a Protection scroll to defend against Basilisks, it *apparently* is NOT properly removed if you Ctrl+R to heal the buffed character. The buff icon is removed from portrait and Record, but you *apparently* retain immunity for over twelve in-game hours. Did not test longer than that, but I moved to a zone 6 hours away after healing and came back, spent more time getting gaze-bombed to no effect. Potentially causes the immunity to be permanent, but would need further testing, and you'd have to check with EEKeeper if the buff could be removed from the save that way.
NOTEWORTHY EDIT: As it turns out, Spell Revisions main component ALSO disables/removes Protection from Petrification as a 1st-circle spell in EET. Likely due to its other changes to Petrification. Removing said component restored the Spell, the Spell Scroll, and the Protection scroll.
WHAT KIND OF HELL IS THIS? So, just looked through Spell Revisions source code again. Turns out the main component is a MASSIVE BUNDLE OF GOODIES riddled with crap like the above 'Petrification Fix' locked into it. This thing DESPERATELY needs to be broken down into separate components.
