is 11.2:1 compression too much for 91 Octane

But tighter LSA increases cylinder pressure and cranking compression thus more likely to detonate.

You have it backwards. Tighter LSA lowers cranking pressure.

To the OP,,,why the 113LSA? I will never understand that.

Call some other cam grinders and see what they say. I'd bet they would laugh at the 113 LSA.
