I did some more work on the engine today. I checked the compression, and only one cylinder was lower (250#) than the rest (300#+). I decided to just pull all 6 heads and do them all. I will have the valves ground, the heads pressure checked, and new gaskets etc. Here is a photo of the rocker boxes (well 5 anyway) and intake manifold removed:

Here is a photo of the heads and bolts off of the engine:
My next task is to find head gaskets. I have tried a few sources, but no luck. I have a post on the VM Diesel group (yahoo) and only one lead so far.
I would like to polish the rocker boxes and intake manifold before installing them as well.
