302 heads on a 360?

What is listed in the books and what it actually specs out to be when you mic it up and do the math are 2 totaly different numbers. My 360 normaly spec below 8.0-1. Many clock in at 7.8-1.
You may get to 8.3-1 with the smaller cc head, but the down size in ports and valve size kill any gain that the compresion would give you.

Bad move to do performance wise.
