Got the motor running and seem to have what we suspect is oil up near the top of the motor towards the rear outside of the passenger side head. I don't believe it's an intake leak, but will confirm.

One thing to note is that the heads are AFR's and when we installed the valve covers, the corners interfered. The rim that the gasket sits on is wider in some areas than the rest, so we ended up bending the edges out slightly. I suspect this is the problem, and if so, what can we do? Probably should of had the extra material removed from the heads, too late to do easily now...
