Default Cam vs Compression

Without boring everyone with specifics, I basically want to know what compression ratio I can safely run. I have basic tuning skills, so nothing on the edge. 400 engine.
I have a 211°/221°/110 cam. Maybe going to a Summit 2801. I have a few options for adjusting compression. With 9.77 CR w/8 vr pistons it detonated. Maybe changing pistons but I don't want to for a mild DD. What would be a safe CR for my cam with the 8 vr pistons?
