318 with 360 heads milling : small valves

I have the 318 in my fury ( 71 engine ) and i have a 77 360 on a stand , i was thinking of milling the heads ( 360 ) to put on the 318 to help me out with the choice of big ports 340/360 aluminium intakes... will it bump up the compression to 8-9ishhh compare of loosing some ( 7-ishh ) thx guys , the 68fury is built to be a simple driver with some "umpfff" and still be a good economy and regular car that can keep with traffic and tow small stuff once in a while ( travelling )..thx !
A lot of this, “How well will it work”, will be the amount of cc’s each cylinder head has. What exact 360 head cc chamber amount you have and what you can reasonably get it down to will be of your interest.

Now here is the good part even before you get into the first half above. The increased airflow will add power everywhere. Tim (318WR) is right on target. I also believe you’re right on track to be concerned about the compression ratio. Any raise in the ratio will be a benefit.
