The chances of your compression tester being similar to that quoted in the green manual are remote. So the actual values don't matter, just that they are even, which they are.
Any engine will show higher value with a wet test - the oil seals well at low cranking speeds, AND contributes to compression depending on how much you squirt in. Your values are still even.
The camshaft will reduce the values.
The head gasket thickness will change the values.
Drive it - hard. If there are no symptoms of an internal fault, all is well. What symptoms you do describe make it sound like it's running a bit lean.
I've ringed as many engines as I have put new pistons in. I do my own honing. None have ever burned oil, and they last for thousands of miles. Hastings and Grant make better rings than Mahle, if that's any consolation.
