Also, I was reading another ls swap into a 4x4 sub of our same generation (by 85burb... I think) and he had a lot of trouble getting the headers to fit. If you go with the stock exhaust manifolds, is it a lot easier, do they fit without notching the frame?

Edit: I saw that your stock exhaust manifolds fit, did you end up trimming the driver's side at all?
