Engine blow by help

I need some help here! I'm hoping to rebuild the motor on my dually this winter but I'm also buying a house so the plans may get pushed back. Here's my problem, the 460 that's in my dually has a bunch of blow by. I went & put a set of stock valve covers on it with baffles in them because the stock one's from 1985 didn't have any in them. I just put a set of headers & dual exhaust on it. Now when I go up a hill it smokes like a Freight Train. It never did it before when I had the stock cast iron manifolds on it. I'm running Rotella t 15w40 in it. What can I do to at least slow this down or even stop it before I rebuild the motor. It's kind of embarrasing when I'm hauling the race car around & it smoking like a freight train! The reason I put baffled valve covers on it in the first place was because it would blow oil everywhere without the baffles in it. Is there some sort of additive I can put in it to help? Should I change to a heavier weight oil?

Check your PCV system. The PCV system should prevent blow by. If the PCV is working properly and you still have blow by, then your engine is shot.

That do's work. So I guess there's no help. I just was wandering if there's a temporary fix until I get it rebuilt which may now be next spring or summer.
