Head Bolts - Tighten a bit more?

I recently replace the head on my SPI motor.. New gasket, bolts and all that good stuff. I ran it for 1k miles and tested the compression..

Cyl 1: 175
Cyl 2: 180
Cyl 3: 182
Cyl 4: 180

Should/Can I attempt to tighten those first two bolts by the 1st cylinder just a tad bit? Or should I just be happy it's within 3% of the others?

Or.. should I first throw a tad bit of oil into that cylinder to make sure the rings are just wearing out?
