Yeah, well, my D17 had erosion on the manifold, which I corrected by face-milling the manifold and installing new gaskets... in this case, though, the manifold runners were perfectly fine, but the erosion was on the head instead.  I'm sure that had someone found it shortly after the gasket blew, they would've fixed it, but they didn't...

Dave - sure looks like you cured the problem! I am inches away from installing a new-to-me manifold on my WD45 - manifold checked out nice and flat - we will see about the head - several of the manifold gaskets were completely history when the old one came off, but I didn't see any obvious erosion like you had. We'll know for sure when we test-fit the manifold.

Okay, the verdict is in:

Milling the head worked perfectly.  Nice, tight seal, no problems.  Lapping the valves was a good idea, too.  She runs well.

Initially, it was leakin' around the head in a couple of places. I let it get good and warm, then shut her down... I went back and retorqued the heads.  Obviously I had a little coolant dribbling in, 'cause it sent up a cloud of steam when I lit it back up, but after that, no leaks or bubbles, and a shutdown, wait a few, restart resulted in no smoke.
