have read you can put 351 cleveland heads on a 351 windsor block, with a little modification because the cleveland heads flow much better. but what i also heard is that the 2v heads are better then the 4v heads because the 4v heads flow to well. is the 2v heads better for the windsor than the 4v heads??? i would also like to stroke the windsor to a 396 but i have also heard that a 400 M crank will work because the main journals are the same. so what do you think, will this combo of heads, block and stroker??? i would like to produce around 350 hp and enough torque to move an f-250 4x4. thanks any information would be helpful.
I've heard many myths about Cleveland heads being put on different engines with some fabrication needed. From what I've heard, I dont' know if there's any solid facts here or not, 2V Cleveland heads are better than 4V heads in SOME ways. Here's a website that might tell you what you wanna know about 2V 4V and Boss Cleveland heads. http://www.boss351.org/cylhead.htm
yes you can put the Clevland heads on the windsor, you will have to plug one water jacket and have another one cut. You will need a good machine shop. Then you get to hunt for a manifold because nothing will fit. This was basically what they did with the 302 Boss engines. But why, Get yourself a set of 289 head with the small combustion chamber, get better valves(oversize) a matched cam & manifold and you shouldn't have troble producing 350+hp. Of course there is much more involved than just that. Ihave been saving a popular hot rodding were they built just such an engine designed to run on 87 octane fuel. When i find it I let you know the specs. They used a 302 crank, so no stroker
It's not a myth, you can put Cleveland heads on a 351W and you can buy a manifold that will work on it. Here's a website that details the process: [link:www.themustangshop.com/clevor.cfm|Clevor]
Having said that, the new generation of aftermarket aluminum W heads are probably just as good if not better in most cases than the old C heads. I'd suggest looking more closely at finding a new or good used set of aluminum heads and putting them on your engine.
Hey Slick,
You've got the right idea but, there a lot easier ways to get a measly 350HP from this baby! They are selling casting from the explorer heads, I think they are GT40+ heads? You can get a stripped set for about $125 a piece. They flow better than any of the old castings. At this point you can get them cut for bigger valves and do a little porting yourself. You'll have to buy valves, springs, keepers, seals, etc. You will have a plethora of intakes/carbs to choose from. A solid cam, an adjustable valve train and a lot of elbow grease, and some Nitrous, you could have peak power around 400HP.
The Cleveland heads work best on Clevelands. I tried it back in the 80s and it just cost me alot of money. Give yourself a break.
Good Luck, Have Fun,

[updated:LAST EDITED ON 13-Jan-02 AT 01:41 AM (EST)] Those are called GT40P heads and I believe that they have a different exhaust port that requires a special header.
I would use a set of TFS twisted wedge heads.They make the most horsepower straight out of the box than any other head,but you must have your pistions checked for valve clearence. My next suggestion would be to use Edelbrock heads. They also make alot of power. If you really want to use a cleveland style head, use a set of Yates heads. Robert Yated makes heads and intakes for these, but they are very costly. Unless you are building a race truck that will only run 3500 to 7500 rpm, the Cleveland head is a bit overkill. Go with a set of preassembled Edelbrock heads with the Big Valves and get the best of both worlds.
3/4 ton truck?Your never going to be satisfied with a small block,then.It could put out 800 horse and still not have the power you want.I know because I have an old heavy 3/4.They are nothing but pigs with small blocks in them.You will never get the torque the big block will supply.An older FE is a "stump pulling animal!",with a little work of course.But, if your willing to spend all that money on machining anyways,I would suggest a 390.Installing a 428 crank alone will make 410 cubic inch.Then get yourself a set of 428scj heads.A decent set can be picked up used for about 600 bucks.Your looking at at least as much horse that you want out of that small block,but twice the torque that you would ever get from it,no matter how much you put in it.
