What sort of heads did the boss 302 use?

I'm trying to figure out if the engine in my mustang is built similar the boss 302.

The Boss 302 used the bigger Cleveland style heads. Looking at the valve cover, the heads will be more square on the ends than the normal Windsor valve covers are.

Cleveland style heads....different than just any 351 heads.

If you have 8 valve cover bolts that is the first clue to being built 'similar' to a real boss 302
