Nope, but the late 80s/early 90s 5.0 motors all had cast aluminum. Far as I know, they all have the same number of bolts. 5, if memory serves. Prior to that, most had stamped steel covers except for some dealer (and factory installed) fancy ones for Cobras, Bosses, and such. Nothing to do with the heads, really - excepting the Cleveland type canted valves on the Boss 302 and 351 requiring a taller valve cover for clearance.
I smile a lot. It makes people wonder what I'm up to...
