My LS comp. numbers....

1. 199psi
2. 200psi
3. 200psi
4. 205psi

Obviously the motor seems healthy, are those numbers about average for a LS?

Healthy numbers there. The main thing to look for when doing a compression check/test is that all numbers are somewhat consistent with only a 5% difference at most between each. When you see one much lower than the others, then you most likely have a problem.
