I'm currently running oem plugs with stock .032 gap. Running 20psi without any issues. Will be going up before next spring to around 28 psi at which point I may need to revisit this myself.
In my opinion, at your levels, even though you are higher compression than I am, I see no need for you to need to touch anything right now.
