The chart is confusing. The first column describes which engine the head is FROM. The next columns give the compression ratio that results if that head is installed on the other engines.
That is confusing, but I see it now. So a '48-'52 327 head will bring the 356 from 6.85 to 7.53. Anything else would be excessive for a flathead running regular.
Note that I'm not thinking in terms of HP, per se, but as I said, efficiency. I would expect fuel economy to be improved a little.
What are the distinguishing marks on the '48-'52 327 head to differentiate it from the others?
