Just got my compression numbers back on the LTR engine in the 02 xstar I just bought. All 8 cylinders were either 156 or 157. Seems good, is it?

380 hrs. numbers were taken at 4500 feet elevation if that matters.

Very good compression numbers. Good rule of thumb. You dont want to have any cylinder drop more than 10% of the average. If all 8 cylinders are in the 150's your golden.
