No, the plug seals are those under the valve cover. There are O'rings under the cam carriers as well.
How can the valve guide seals be missing? They are not easily removed unless someone forgot to reinstall them when cylinder head was worked on.
What are the compression on all cylinders?
Were the valve clearances checked and adjusted?
Do you have oil in the plug tubes?
