my friend has a 65 fastback with a slightly modified 302. they are planning on restoring the car ground up sometime soon. my friend has mentioned several times that his dad wants to drop a boss engine in but doesnt want to cough up the kind of cash people are asking to buy one. he has been looking for a decent price but has had no luck so far. so i was thinkin why doesnt he just get some cleveland heads and put them on? then it will be a semi-boss right? this is where the questions start.  what has to be machined? the heads, the block, or both? how much would this cost? they are 4v heads too right? and would it be cheaper and more effective HP wise to buy some aftermarket 302 heads? this is just an idea from me and thought i would look into it. if its not that expensive, it could be as close to a boss as he can get. OH, just remembered, the heads will create more HP i know, would the 2 blot mains be able to handle this? just curious. thanks.

Thats a link to an article written on how to do it.I would think it'd be more effective to just get aftermarket Windsor heads.

Forget the Boss302, build a stroked 302W it will out perform the Boss302.

It's alot of hassle to build a boss motor unless you were doing a total rebuild.The boss has different pistons for the canted valves and has the longer 289 rods.Your intake selection would be pretty limited as well and you'd need the boss manifolds or headers as they are different as well.It would be cool to have a "boss" but I just don't think it's practical unless you had most of the pieces.I'd just go with the aftermarket windsor style heads. ------------------

The 351C heads on the 351C in my '66 F-100 aren't cracked. It runs just fine.You only need a Clevor intake with Cleveland heads on a 351W block. On a 302 block you would use the stock Ford Boss 302 intake. Tracy ------------------

I have seen,had and built many a 351C engine and cyl heads.I have never seen,nor heard of them suffering from cracks.
Just exactly what year heads are you refering to in your statement..????You would need a special intake if you use 2V heads on the 289/302.A Boss intake would work on the 4Vs

I have to say my shop has rebuilt five 2V Clevelands and two 4Vs in the last two years. We always get the blocks and heads hydrotested, and they've all passed - so that's 14 out of 14 so far.

I've heard of the webbing cracking around the cylinders on the clevelands. But all three sets of cleveland heads I have, have no cracks anywhere. I do however have a weiand tunnel ram for the 302 Boss engine if you're interested in it. Shoot me an email.

Not tryin to upset anyone, but in USA,
Where Ive worked, Ive magnafluxed more
than a few heads. Clevelands almost always
crack across the exhaust valve seats. This
is pretty common in the trade, or it used
to be. Don't see to many anymore. Their
mostly obsolete. Oh well

I don't think anyone is upset, just news to some of our ears. Just in most of "our" experiences, never had problems with the heads for the most part. Either way, you take a chance anytime you start trying to build horse power. That's the fun of it.

Good point. Just tryin to save you guys
a little grief. I've read, years ago the
Aussy heads were made out of thicker
castings. Don't know for a fact, as I've
never seen one. As far as the port design
the Cleveland heads look a lot more well
engineered than the Windsors. {>:
