I remember hearing about this, but don't know if it was Cleveland or Windsor heads that people use. Which heads do people sometimes use on 5.0's? The reason I ask is that there is a guy in town who has a ported set of 351W heads and I plan on getting a set of heads for the 93 'GT someday, and I am wondering if these would be good for the price.

The ad: "Im selling a set of ported 351 Ford Mustang Windsor cylinder heads. Installed are 1.94" intake valves and 1.60" exhaust valves, PBM full roller 1.6 ratio rocker arms. It comes with steel guide plates, dual valve springs that have a 160lb seat pressure at 1.850" installed height w/ titanium retainers, and big 7/16 rocker arm studs. Everything is rated for a massive .600" lift cam. These will make some serious power, but I need money for school. I paid over $500 for just the valvetrain not including the bare heads and port work."

My car is stock except for the exhaust/short throw. Would what is on these heads be good for a stock motor (I plan on adding a 65mm T/B and cobra intake or explorer intake in the future)or are the springs and seat pressure totally incompatible?What kind of horsepower versus GT40's (iron), or just stick with those?Would they clear MAC stubbie style headers?

Also, GT40's (iron)or GT40P's I have heard that P's make more power...What is the difference there, and what headers typically clear those? I have MAC stubbies for the car...

Thanks for your help. I don't know much about spring pressure and using the 351 style ones. I was going to save up and get some trick flow twisted wedges, but after seeing that summit article, I think I am just going to go with the hopped up GT40 parts and save for a stroker in the future, something to start fresh with zero miles on it.

Thanks again... Also what are they worth...Roller rockers look brand new, heads look like they have been in the washer, look good etc.$$$???

351 Windsor heads. You'll need bolt reducers since 351s use larger head bolts. I think regular GT40 heads flow better though.

regular GT40's flow slightly better than unmolested 351w heads, but seeing as how these have 1.94/1.60 valves they have obviously been opened up which means they will definately outflow GT40's

i dunno what he wants, but with the rockers even used i would say if they are in bolt-on condition they are worth an easy 500 bucks

how much would the extra hardware run for the bolt reducers? Also, now what valve covers would fit these? He's asking a little more than $500 but I would def. try and talk him down.

I did run in to a guy tonight I haven't seen in awhile who owns a shop and he said he has a pair of twisted wedge heads that he got for $160 bucks for a 289, but should fit the 5.0 no problem, correct?? he said they have minor port work, but need to be cleaned up and rebuilt, needs new springs (he has stock ones, but would probably just by the trick flow spring kit rather). I don't know what he exactly wants for them, i would try and trade some items first, but I asked him to check the part# for me, or he may bring them buy to look at. He thought that the 289 style head had a difference in thespark plug (location?)and though these were like 47cc (I believe he was talking about combustion volume) but I believe they are around 60cc. Anyway, it would be nice to get these cheap just to have them.

the 351w and 302 used the same valve cover, and the trick flow heads "stock" springs should be trick flow springs anways - as long as they are they should be good for about .550 lift. the trick flows would be a much better buy if you can get em, but the 351's would also be good if the trick deal falls thru.

Sounds like another kid, that bought an engine part and didnt realize what he had to do.

Make him a low ball offer,


Reducers $35

Gaskets $75

Oil, Coolant and Brake Cleaner $30

Camshaft= Keep stock camshaft, put on some 1.7 Rollers.$180, but transferrable when you upgrade later

Thanks for all the input all. The tricflows actually need to be rebuilt per the current owner, and he had a set of 5.0 stock springs aside for them. I haven't seen anything yet, hoping he brings them buy soon. He is actually from Sweden I believe (that's where he got the heads) you would think that they would have went for more than $160 there considering they had to get shipped over there etc. Even though they are used he stole them for that price!

my77stang

really you dont *need* head bolt reducers, all you really need is to use a grade 8 washer under the head of each bolt. contrary to the popular believe it does not matter because the alignment dowels keep the haed aligned to the block, and all head bolts do is CLAMP the block and head together.

Also just to so everyone knows you can also mount 351C heads on windsor motors(289/302/351). Known as a Cleavor. Clevelands are well known for their heads.Theyflow much better then 351 Windsor heads. If you have seen the size of the ports on a 351C head you would know what I mean. Think of a351C headas a 32V 4.6L and the 351W as a 16V 4.6L. The Cleveland is more of a high winder with a softer bottom end while the Windsor is a grunter head with low end punch anda choked up top end. Its a much more expensive conversion as you need a special intake. Its a pretty trick setup that if mounted on a 302 gives you a very similar setup to a Boss 302. Boss 302's used modified Cleveland heads which were then later reused on the Boss 351.

those older 351 heads ('69-'70) are casting number D00E and pretty much ARE gt40 heads

p's will not clear headers w/ out midifying or getting "p" specific headers

here is an ad i just saw in my local dragstrip forums, remember these are completely bare

Good pair of 351w cast iron heads, no valvetrain but a good workable casting for a tight budget. Asking 100.00 or best offer. For more info call 517-605-3784
