A 4mm stroke will increase compression by .4 approx. So a 11:1 piston and 4mm stroker will yield about 11.4:1 total compression. Of course, this can be changed with the thickness of the base and head gaskets. I ALWAYS use a factory head gasket. 93 should be safe, maybe even 92 at sea level. If you're concerned about compression you could machine some of the 'dome' off the top of the piston.
