Help oil leaking from head

[yeahyeah1469]

[/B]well i finished my build and i started my car and it was boosting and running sexy when i saw some light smoke which i thought was just oil cooking off the parts .... well it got worse and i noticed my exhaust manifold gasket had oil around it only on the cylinder 4 area ..... i took off the manifold just a min ago and what do you know oil caked on the inside of the exhaust port on the head ... please shed some light on a fix for this problem its a 1991 GSX 6 bolt just in case that helps.

Valve seals?

laserspeeddemon is right, I think that it is valve stem seals also.

Yeah, usually if you see oil leaking from your exhaust ports on the head its either valve stem seals or cracked, worn out valve guides.
