I reread your 1st post...
The 2 holes from the bottom are nipples from the top of the valve cover chamber and I believe are part of the PCV system. I'm not sure why you see exhaust from there...I never pulled mine off while the engine is running... If exhaust, it would have to slip by the cylinder rings and valve guides, or maybe the exhaust valves are out of adjustment...maybe what you see is gas/oil vapors of uncombusted fuel?
