Compression numbers Ross 8.5:1

[talonpower]

Just did a compression test yesterday ...

Ross 8.5:1, Mitsu 3 layer HG, head recently resurfaced etc

its a magnus stage 2 motor with about 8k on it


Cyl 1 Cyl 2 Cyl 3 Cyl 4
178 167 176 176


are these numbers "excellant" or "good" .... i know the 10 psi difference isnt huge but what if any difference in performance would this make and is this something i should be worried about??? again, the motor is basically brand new so i was hoping for very close to identical numbers in all cylinders

thanks

Yeah those seem pretty good to me.
