Headers

[88Vic]

Just know that NONE are direct bolt on. O2 sensor harnesses will need lengthening, bungs for the O2 sensors will need t obe added to the exhaust, and the exhaust will need to be modified to have the headers fit. YOu will also need to find a way to attach your dispstick, air filter box, and some othe things I am forgeting.

Does that also apply the stock Mustang shorties or just aftermarket headers?

As and aside: will equal length headers indeed fit? Any thoughts on whether they'd fit a 351 car?

If you can find equal lengths that are intended for a 351 swap, I should think they could be made to fit...

Both.
