What happen !?


It smoked a little out the right side exhaust..
every time I have had those heads on it smokes
a little.. I thought I had it fixed(a hole in the
intake runner).. it was just super thin where I
clearanced the push rod.. I tubed that but there
must be something else

And you pressure tested them ???



Pressure testing them is good for water issues, not oil issues. From what I've read the W5's are porous to start with then we add porting. It could be leaking from a valve spring pocket, bolt hole, pushrod pinch, or about any where else oil is close to.
