oil leaking around spark plugs flat 6

So you are running the Autolite 306? Throw the "someone told you" crap out the window. Run what the book says. Do the plugs have the metal gaskets on them? Were they tightened properly?
yep they have the metal ring reading and looking around it says it calls for this plug as far as torqued i dont know what they need to be
