I'd use the performer intake over the torker.
and the Holley 600 4 barrel
The roller rockers are a must.
Then up the rear gears to a 3.73
A small cam would wake it up too, a comp cams high energy 268 would be a good choice w/ matching springs of course.
I would definetly invest in some headers too, I'm pretty sure that year fox bodies had cast iron exhaust manifolds on the v8's.
I'd hold off using them 351 heads for now and save up for a complete build later on.
