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 called a 95 svt cobra R 95 saleen s351 95 saleen s351r code. naw your right no mustang came with a 351 my bad

if dude had the money he would notice a big difference more than the 35hp your stating ported

if the saleens came with the 351's do they count as part of the engine swap laws in Cali?? Doesn't affect me in any possible way, just curious

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.
very simple. end mill and about 15 minutes of work per hole. nothing tricky there about 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.
