Heads need resurfacing after only 15K miles.
 

There was slight, very very slight pitting around the outer combustion chambers. So whamo, another $50 in machine work.

This time I will run a sacrificial annode.

What is a sacrificial annode?

When you run Al heads on an Fe block there is some bad electrolysis that takes place. Causes corrosion which can eat away at the heads, basically very minor pitting. They'll only need to be taken down .001-.003 IMO.

The annode attracts the electrolysis and wel... sacrifices itself rather than letting it attack your heads. You can also ground the heads directly to the frame as a preventative measure, I will also be doing this.

Got the heads back, had to be taken down .004" I was close.

The heads are so pretty and shiny now :D

Shiny good!

Dull. . . baaaddd.

If only my deck were as shiny! I wouldn't need to spend several hours with the scotch brite pad!
