170 seems fine but a leak down test at TDC is a more important test.
driveable for street only...recheck in abt 5k...right now give each cyl ONE shot of motor oil and check compression all to determ rings vs valves going south.
Near or at the top of the cylinder is where most of the wear occurs, as this is where the piston and rings take their beating, seems the most likely spot to have leakage past the rings.
