I'm using a 1996 mustang GT donor car with a 4.6 motor. Can I use aftermarket BBK shorty headers 16150 with the J pipe that comes with the basic kit? Will these headers interfere with steering shaft? Do I have to use the headers that Factory Five sells.

Can I use the stock oil pan, or is the canton short pan required?

I'm still dismantling the mustang. This is going to be a long, long project. Thanks for your input.
