cleveland heads on a '94 F.I. 5.0?
cleveland heads on a '94 Fuel injected5.0? is it possible? smog legal in cali? what are the benefits/problems running this setup? how much power do they make? the reason i ask is my boss has a set i can get for cheap. they are the 4v design with huge runners and closed wedge combustion chamber.

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

whats he asking for the heads? may be a good buy just to flip[8D]
btw, they are high revving screamer heads - too big for the street without port tongue/riser things which defeats the purpose of getting the 4V cleve heads to begin with.
they do look sexy as hell though

they can be done however you have to have the block sent out for major machining. water passages need to be drilled and a bunch of other things. the original boss engines where 302's with cleavland heads on them. so in the end its not worth it at all.

1st question. What are you going to use for an intake?
2nd question. What are you going to use for exhaust?
3rd question. Do you have the $$$ to custom make the above?
If you can get them cheap, buy them and then sell them and use the $$ to get a set of heads designed for the 302.

if there is machine work involved on the block, then im not gonna do it. i was just lookin to get some cheap perfomance heads. i probably would have done a ported typhoon intake and short tubes along with them. (combined with my existing mods) -----thanks for the advice everyone, i would have been pissed if i bought them and found out i had to machine my brand new block!

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.
CHI makes intakes for carbs, so you'd have to use a spyder's elbow type thing and hook throttle body to that, and headers would be swap headers or custom. so yeah, its possible to do - but no, for what your doing its not the route to go.
