Porsche Crest Lowering High Compression

Anyone ever heard of lowering the compression ratio on a 912 engine using shims under the cylinders?

My high comp (10.5 to 1) runs 98 octane fuel here in Oz, and having to detune it as to keep detonation to minimum, I want to try something else. (not twin plugging)
