Urgent Please Help!

They are considered "stock height" for an 87-93' Mustang. The SN-95 Mustang valve covers are slightly shorter. You can actually fit stud mount rockers under stock 87-93' valve covers if you cut out the baffle mounts. However, stock 87-93' valve covers usually interfere with the alternator on an SN. The Trick Flow valve covers will definately clear pedastal and stud mount rockers as long as you don't have a rocker girdle, which I suspect you don't. If anything, they will interfere with the EGR valve, if the car still haves one. You might have to do some tweaking to the EGR setup to make them work, but it's as close as you're going to get.

The problem with the SN-95 cars is that they only made them for 2 years with a 5.0 engine. None of the aftermarket companies bothered to make valve covers specifically for these cars because of low demand. You're always making do with a Fox valve cover.
