grayish/white color valves?
Hopefully its a gasket and not a cracked head. I remember when my brother cracked a head in two different places, and melted the sensor to the head. And by the way, he said that the engine never overheated...hahahahaha...ok. Cracks can sometimes happen right underneath the valves (where they sit), so take 3 and 5 off to check them out. Good luck on the repairs.
waitin fer spring compressor ta git here, but 3 and 5 def comin off. gonna pull all, have head checked. overheated just a little few months ago, but nothin too bad. should be fine, but that's alot of work for a should be. i'll make sure.
