Per MSD:

Compression--Spark Plug Gap
Up to 10.5 -- .050 to .060
10.5 to 13 -- .040 to .050
over 13/1 -- .035 to -.045

They note to open gapes in .005 increments and test untill best performance is obtained.

7/1CR with 1 bar is about equal to 11/1 effective compression.

I know your system is stock but this is an interesting example of what can be done with spark plug gaps.
