After I removed 40+ securing bolts on the top of the head, I was able to *very* carefully pry the the top of the head off. I noticed immediately that there is no gasket or sealant in the head - not even around the perimeter.

I purchased a tube of volvo liquid gasket for this project, should I apply a thin thin film of liquid gasket around the edged of the upper head when I reassemble the engine?

Obviously, one must take great care to avoid plugging an oil hole.

With the intake manifold off, I can see that the whole engine is grimy with oil/dirt. Could the engine crud be a result of lacking a seal on the upper head?
