Compression test on a 360, result OK or not?

try a vacuum guage
how's the timing chain, oem stem seals?, how do the plugs look
good day slanty! I'm cool

I have a vacuum gauge, needle flapping 1 inch at idle in gear.

Vaccum is 18 inch in neutral and around 16 inch(jumping) in gear.

Timing chain is double original on these, low mileage as well, should last longer than 40 000 miles?

New valve stem seals installed recently.

All plugs look like this:
