8V loss of power, lean condition?

After my burned exhaust valve and what seems like successful repair (machined head, polished valves) the symptoms remain. When under high speed (90+ mph) and under WOT the car looses power. Even with APC soleoid disconnected, hence base boost!
Today I have pulled the plugs, taken some photos. Please look at them and tell me what you think. 3 of them seem suspicious to me.

Compression readings are good, 160/155/162/160
The vacuum/pressure enrichment port on the warmup regulator holds vacuum.
What to check next?
