Spark plug reading

Figured I would post pics(as best I could) of my spark plugs after approx 200 miles on my newly built 340. I was rechecking valve lash and figured I would post plug pics while they are out.
Hopefully to gain some insight as to fuel and timing.
**Disclaimer** plugs were new NGK BPR6ES, but the 1st 20 miles I was dealing with a lean issue and elec issues.
Specs are 340, elec ign, timing is 18* BTDC with VA plugged and disconnected.
Pics are of 2-8.
Thanks
