I was thinking about that as well. I have never gauged what the boost in compression is when I remove the headgaskets. Could be a 10 lb gain or maybe a 30 lb gain.
You gained 10 lbs by removing it when maybe you should have gained 30 lbs but its farting out around the head so most of your efforts may be canceling each other.
I always keep a spray bottle with dish soap and water handy to spray on possible leaks so I can see the big bubbles.
