The Cyclone I design includes no timing assignments for interfacing with the ASRAM. Maybe the Cyclone II design needs such timing assignments or contstraints.

I'll let someone else give you help specific to your design. To be proper,
every design should have every internal path and every I/O path constrained even if Quartus happens to give you the timing you need without constraints.
The Fitter uses the timing constraints. Depending on whether you have the design partially constrained or not constrained at all for timing, the Fitter might not be giving any effort to performance. You probably got a compilation message about that.
Even if the real design requirements are very easy for the Fitter to meet without optimizing for performance, a proper design is fully constrained so that anyone looking at the design knows the design requirements and knows whether those requirements are still being met in the future when something changes that could keep those requirements from being met by chance.
