I recently changed my head gaskets and intake manifold gaskets. I am having oil coming out of my headers, could this be the head gasket did not set right or is broken. Or would it be the intake manifold gaskets. let me know your sugguestions.

If you've just replace the head gaskets and intake gaskets and you're sure that they are sealed really well, then start looking at valve adjustment or valve guide seals. If it blows oil all the time then chances are your problem is not valve guide seals. If your valves are not adjusted correctly they may not be closing all the way allowing oil to enter into the cylinders. Just a suggestion.

Ok when you say check the valve adjustment. Do you mean the valve lash on the rocker arms. Or is this something else. I have never removed or replaced the valves.

I could have to tigthened the rocker arms in the right sequence maybe

yes. valve lash. i had the same problem and that is what is turned out to be.

its been a while since i've messed with mine so i can't tell you what they are supposed to be set at but that was the problem with mine.
