Default head or vavle cover leaking oil

What do you guys think. Do you think the vavle cover or head is leaking oil.




Thanks

Tough to tell without any pics of the valve cover, but it looks like the head gasket, unless it's leaking further up and just collecting there...

Mine does the same thing. Mine will stay wet around the exhaust ports. Motor is coming out soon enough though.

It's hard to tell from the pics, but it almost looks like the oil "wicks" up the threads of the head stud, then runs down & collects on the gasket. You could try some teflon sealant on the threads.

Could be thats all it is, and really tough to tell by the pix, but looks alot like gasket. How much boost, is it stock motor and how hard u beat on it? Is that the only place u have oil? Any pooling on valve cover bolts?
