 It's funny Tim mentions silcone because when I rebuilt my head it had a ton of sludge trapped in those tiny oil passages. I could not get them out, even with high pressure water. I ended by having to drill a hole in the other side of the head so I could use a long stick and push the silicone bits out. The old silcone gets brittle and breaks up into annoying chunks. Then I threaded the hole and plugged it up, so now I have three plugs.

Definitely oil, not coolant. Coolant I would look at the water pump again, there are little bolts holding it on and the gasket originally used is pathetic. I put a new one on with a new water pump and it still leaked a bit, until I was able to tighten it down after some heat cycles.
