Compression

How much compression is too much for the street, before detonation presents a problem? I am putting together a new shortblock and with the W-2 heads @58 CC I will be running a 11.5:1 compression using a .051 cosmetic head gasket. Now I have always run 94 octane with a mix of octane booster, or even possibly some racing fuel occasionally. I generally only drive the car 600-1000 miles a year. Should I take steps now to get the compression down to 11:1 or 10.5:1 for a more streetable combo?
Thanks for the comments,
