Picked up the head today. im taking no chances and had the head surfaced. Eisele's did a great job at cleaning it up to.
The head had been cleaned pretty good so I removed the caps on the cams and re-oiled them.
Here the head lay back at home on the block.
now the tedious task of putting it all back together.

finally got it loose:
the headgasket looked ok but there was water/oil on it so it's bad somewhere. the cylinder wallls are in great shape.
what is all the flaky stuff on the pistons? the red stuff is rtv but there are flakes. I can just blow it off, looks like maybe sediments from the water it was burning.

The flakes are built up carbon deposits over time.You probably had some build up on your exhaust valves but it was black.I'm guessing your gasket went between cylinder 3 and 4 and its a tiny hole that grew.Ive been in your situation before but it was due to overboosting and running lean also.

$80 for the resurface and the labor for them to remove the valves on the intake side. had it back the next day, they also cleaned it up rel nice.
