Thoughts on this oil seepage

Either the valve cover rails are contacting the intake runners, or Some of the valve cover bolt holes are open to the valve cover area of the cylinder head and need sealant. Possibly both. Very simple fix. If you see the valve covers are hitting the intake, just mark the valve cover rail in either site of the intake runner pair and knock off the bottom of the valve cover lip in that area. Then of course simply put sealant on the valve cover bolts. The intake bolts don't appear to be leaking. Those are always the ones a lot of people forget to put sealant on, since the do go right through into the valve cover area and oil will migrate up the threads from crankcase pressure and puddle next to the bolts on the intake. That does not appear to be the case.
