Camshafts and Compression

Got a decent drive in today, not a hint of ping. Ran smooth, pulls hard with the secondary’s in. Timing is at 20 initial, 34 total, 12 vac. Vac is on MVA. Tune looks a bit on the lean side

The plug looks cold to me.

And it’s not lean. At least at idle and cruise. No one can see from those pictures what the tune up is like at WOT.
