Compression Test on my 318, not good

Let's go with "not broken in yet".

Drive it around and put some more miles on it. Then do the wet and dry compression test again after a few months to see if it gets more stable. If not, you can always do the rings later or next winter.

This ^^^^^^ you really need to listen to the voices of experience on this. They are telling you the right thing. Keep drivin it.
