67, we didnt do ANY porting or welding ont he head, thats completely against the rules - just had to install smaller seats because regulations stated the largest valves allowed were x.xxx and the stock 4bbl valves were larger (all the chevy guys are hogging their heads out to get that big, and here we are downsizing).
i'll tell you why it grenaded, its because the owner of the company was a dipshit and wanted all 8 cylinders sleeved so we could go with a huge overbore, then cemented half the damn block. did i mention this was a REAL boss 302 block too? i wanted to cry watching it get molested like that . if he would have allowed us to keep it at a .030 bore we would have been just fine. going up against #906 chevy heads (later model vortec heads, which are the best cast iron gm has ever made) we were dominating - and that was the only ford there because even the gt40's cant keep up with the 906 heads
That sucks to trash a block like that! Cleve heads can be good for stock/mild mod class racing, but I really dislike them for street performance. The ports are all wrong for a street performance head if you want to get the best out of an engine. Like I said before, they work ok, but I get aggrivated when people think that stock Cleve heads are the greatest thing since sliced bread. And as far as GT40 heads, they are the best Windsor style head Ford made and work with mild street performance stuff, but yeah, they're just not enough to compete with some of the stock GM heads. GM has really gotten the formula right with the new LS heads though, good flow, good velocity, work very well right out of the factory. Take a stock LS1 and swap in a cam and a better manifold/exhaust and you go from 315hp to well over 400 easily, streetable on pump gas without even touching the head(except maybe springs for the bigger cam) or having to turn a lot of rpm. The same can't be said of small block Fords unfortunately, it takes a fair bit of head work to achieve that

ok so it official i am going to rebuild the cleve.... honestly i was really leaning in that direction i was just looking for some support behind me...
for those who have rebuilt a cleve or knows someone who has, what was the combo used, obviously CHI heads are overwhelming popular, regardless if Edelbrock is stealling the design from CHI if there pritty much equal im gonna go with the cheaper of the two, i feel that Edelbrock is just as reputable.
anyone have any advice on manifolds or anything else that would be helpful... thanks

Actually, CHI heads are NOT overwhelmingly popular(at least not in use on vehicles), most people don't get them because of the price(which is foolish, because the power they make actually makes them a better deal than any other head for the hp/$$), but they are simply the best bar none. As far as power potential, even the small CHI head with the 185cc intake runner is capable of 600+hp EASY(ie Engine Master's challenge made 605 with a flat tappet cam and pump gas, so imagine the power with a comparable roller cam). You could always get a bigger head, CHI does make them quite a bit bigger than that(up to 258cc out of the box, and they have CNC porting available as well. If they can get a 366 to spit out 600hp with a 185 runner, imagine what it'd do in race trim with a 258 runner!!!). And as far as performance, the CHI head is quite a bit ahead of Edelbrock's or anyone elses for that matter. You get what you pay for really, you spend less on heads you'll make less power, you spend more on heads, you'll make more power. It depends on how much you're willing to spend and how much you really want the power. If you have the money I say go with the CHI heads/intake, you'll be lightyears ahead of the competition

I am cunfused, you are going to replace a 351W with a 351C? I like the Cleveland and I am rebuilding one now but that is what came in my car. If it came with a Windsor I would have rebuilt that. I have a 429 CJ with no home and I thought about dropping that in my 73, but figured it would just be easier to keep the 351. Everyone is talking about big horsepower, is that what you want? Is your Windsor a 69? Those are supposed to be the best ones.
Do what you want, it is your car. I think either one would work well.

yeah i am going to replace my 351w for a cleve neither came with my car, when i bought my car it had a 302 and that wasnt even the original 302, so at this point im not worried about what was the original engine i am just wanting to get some power, my goal is around 400-410hp thats where i would like to end up when the rebuild is complete...
if i went with those CHI heads would i be better goin with the 2v or 3v heads what whats the difference ??

the 3v is a hybrid mix of the 2v and the 4v

1971 Mustang Grande project. 425hp 426 Ft-lb 377" Cleveland with CHI 2V heads & many other goodies. Broader built FMX transmission 10” custom converter. Maier racing suspension, 31 spine 9” with Detroit True-trac, more to come.
With the CHI 2V heads you can run any 2V intake you wish to.
With the CHI 3V heads you must run their intake manifold, also the 3V heads are available with three different intake runner sizes. You can go as nutty as you want to, the shop that built up my 377" 2V also built up a drag motor for a fellow in Redding, CA with 3V heads. They were expecting about 650+ horse.
You will probably spend about $3,000 on heads and intake if you go with the CHI setup.
The Parker 4V intake is only $450 + $100 for the tongues. Then all you need to do is find a good set of 4V iron heads to rebuild, should be about half the price of going with the CHI setup. Might be something to consider.

RE: 351 cleveland rebuild?? - 
. if he would have allowed us to keep it at a .030 bore we would have been just fine. going up against #906 chevy heads (later model vortec heads, which are the best cast iron gm has ever made) we were dominating - and that was the only ford there because even the gt40's cant keep up with the 906 heads
