Your calculation is close enough. You are about the limit of 92-93 octane in the pumps in the US.

The closed chamber head Clevelands are particularly sensitive to octane. You still may need to limit total timing and more likely the rate of advance but you can't know that until you are up and running.

You do not want any more static compression so use standard thickness head gaskets.
