Oil Pan Removal

Today i had a jack slip and my car dropped down and the jack pushed the front of my oil pan in . I'm wondering if there is any way to get the oil pan off without pulling the engine? If not then this gives me a good excuse to put the PI heads that i'm getting in this week right on my car and i'm looking for a cheap set of headers to put on the car while the engine is out. Thanks for any help that anyone can give me.

Yeah i'll probably just wait till i get a chance to lift the engine out and swap out the head while i'm at it. I still can't beleive i made such a bonehead mistake.
