356 CI Compression Ratio

I understand the compression ratio on the '48 356 is only 6.85. It seems this engine would run more efficiently at around 8.00 being that's what the later 9-main 327's ran. It appears swapping heads with any of the smaller displacement engines only lowers the ratio further. I'd like to hear thoughts on this topic.
