Hey guys,
I talked about this with my dad and he thought maybe the headers are causing the head gaskets to warp and let oil seep? The check oil light has been on and off intermittently since the last change (maybe June?), and I added 1/2 a quart around Thanksgiving after the dipstick showed the level a little low. The light went off, and I haven't seen leaks under the car, but as the pictures show, there's oil around the head (driver's side).
Oil seepage?

Looks like leaky valve covers to me.
Try some new valve cover gaskets.
Get the ones with the metal core so they don't squeeze out from under the valve covers.
I always glue my valve cover gaskets to the valve cover with a good automotive gasket adhesive and wipe a thin layer of grease on the gasket side that touches the head.
That allows the gasket to move a bit during fastening down and during the expansion and contraction of the engines heating and cooling cycles.
Plus when/if you have to replace the gasket again, it is stuck to the most easily removed part.
While you have the valve covers off, be sure to check the intake gaskets, especially at the front and rear which are usually the most likely to leak.
The headers will not affect the head gaskets.
The factory exhaust on a lot of cars is tubular, just like aftermarket headers.

My bad TH, I meant valve cover gaskets - not head gaskets! Looks like I've got a project to tackle before I head back to school. Thanks.

One of those, "Don't listen to what I say, you have to know what I mean" things eh?
P.S. I have those frequently.
They really won't affect the valve cover gaskets either unless you have a leak that is blowing directly on the gasket area.

Yes, I have seen the header gaskets leak at the top where the header is bolted to the head and it will eventually "cook" the valve cover gasket.
