Can compression be too high?

[VRMAN]

I had the compression tested on my 1991 when I had my mods installed and the compression was:

180-165-165-165.


I thought factory compression was 160?

Could this be harmful? Thanks.

carbon deposits most likely,
try some mccc

but 165 is damn near perfect for a 1g, i wouldnt be to worried about it
