Re: Exhaust manifolds/headers
Hedman Hedders 88400 will fit. Make sure that you paint them with high temp paint, as the paint applied by Hedman will burn off in a few minutes.
Dougs and hooker also make headers that fit, but cost more then the 88400.
And as you found factory mustang headers will not fit. Also 1960's mustang headers will not fit either.
