is 11.2:1 compression too much for 91 Octane

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.

I bet they wouldn't. nor would one of the best engine builders around.
