The difference between the fox headers and the sn95 headers is that the '94-'95 5.0's used a tube mounted to the header for the EGR where the foxes used the internal EGR ports in the head and intake.
So, if you're doing an EGR delete or doing a fox TB conversion, the fox headers will be perfect for you (and cheaper )
yes they will work but you will need to cap off the spot on the EGR where the tube goes, and as long as there not L/T's only the equal or unequal lenths will fit from afox. peace
