Q about starter heat shields

[5.0 Fiend]

Yeah, I guess I'll need a timing light, where do you point the gun at after you hook it up? The harmonic balancer? I never noticed any numbers on it.
Next up, what year stangs had the mini starters? 94-95?
As for my exhaust, it came on the car when I bought it, the headers are rusted, so they must be old, (did 84's come stock with headers?), then I've got the standard exhaust going down by the front wheels where it connects to 60 inch six sided glasspack chrome shielded side dumps.
