Yes they have tight ring gaps but if the compression was a point lower like the LT4 they would tolerate a lot more power on 93 and likely be less failures.

Upgrading fuel system is a big commitment.
I would upgrade the Cam also.
It just seems when you get close to 600whp it is exponentially more expensive to push past it than to just let it be at a "safe" level based on what kind of octane is available.

Aftermarket is still atrociously expensive for alot of parts on 6th gens
