Head gasket blown?

Which cylinder(s) are spitting oil?

I had a valve seal issue on 5 cylinders with my fresh cyl head/valve seals. Replaced them with 3921640's and no problems since:

gonna pull the manifold off and see. Those are the seals I put in when I did the the head gasket I'm pretty sure.
 
Pull the valve covers and see which seals you have.

My machine shop installed these seals:

They were leaking on 2-6..

Edit: The valve guide seals all appeared to be fine. They were installed securely, but still leaked.

Wash it up with some parts cleaner and turn the engine over so that the piston of the cyl with the bad seal is at tdc. So the valve wont fall and change out the seals one by one on the exhaust side of the two cyl.
