Boosting a stock gsr is common, regardless of compression results.

When performing a compression test, consistency is more important than psi. As long as the numbers are relatively close, (I think 8 psi is acceptable), your engine is healthy. By looking at those numbers, I would say that your motor is in great shape and it can be boosted. It doesn't get much better than that my friend. Congratulations
