Following my several gx390 questions, this is what happened:

I order a racing head, with more compression and bigger valves.

After inserting the racing head and the reinforced pushrods, engine works fine but after 5 minutes i get engine oil everywhere, seems that oil leaks from engine block.
 
Unless there is a hole in the block there are only 5 place for a leak .
You added a different head . Now it leaks oil .
I would check the head gasket . Area of concern is the pushrod chamber sealing on the gasket .

Do you have your valve cover vented to a catch can?
 
ok, the head gasket was placed in the wrong way. it´s stupid but it happened.
The oil from the engine block was not sealed and was spilling. Lesson learned. thanks for the replies.
