Most in the know will tell you that consistency between each cylinders tells more of the story then the peak number since gauges/test conditions vary. Your numbers are very consistent. Try a different gauge if it bothers you and want to be more sure. Its not a hard test to perform yourself.

the consistency is good.

but for peace of mind, a leakdown will confirm.

Excellent! Photos were a good idea on his part.

I am convinced this car is good. That HF gauge reads way low. I got similar readings, but when I used a decent gauge I was in 230 range...
