first off, no they are not
the smog law states that any part must be available in that model year on your particular model, since no mustang had a 351, you can't do it and for sure get away w/ it
second, will they work ? i'm sure they could but i doubt you'd even see a diff, your better off w/ gt 40 irons off a '93 cobra
after all the work you did, using old heads made to run leaded gas will not pay off in the end.
dooe casting '69/'70 windsor heads are gt40 heads basically, but same thing, need some work like hardened valve seats etc.
a head swap like that might get 15 hp box stock, 35 w/major port work, but you have as much or more than buying used aluminum heads.
yu can find them all day long for $800 or so, i have edelbrocks i'm selling right now $800, and my buddy has afr 165's for $1000 brand new

its not so much the block machining, its the head machining thats tricky (turning a square water passage into a round hole so you can knock a freeze plug in it.

well, having a really heavy duty drill press with a large enough table to clamp the head down comes in handy. even the peterson seat and guide tables with a floating fixture we used in the machine shop would wanna shake around a bit when doing stuff like that, and since you have to be able to install a freeze plug in that hole it needs to be as concentric as possible.
