ok i was woundering if any one had any exspereance with my dilema.
ok here goes I have a 1976 ford F-250 hi-boy and am currently building a 390 Fe motor, i punched it out .030 over and have a simple power max cam in it and i need alot of head work done i need all guides put in so i decideding on a set of 428 heads with 2.060 intake and 1.65 exaust valves with soft seats( all valves and seats and guides are new). The head codes are EDC 6090E Does any one know what this acualy is? The guy wants 400.00 for the set is this a good deal? any other coments on how i can squeeze out any more Hp from this motor? <img src="graemlins/evil.gif" border="0" alt="[evil]" />

I dunno dude. Doesn't look like any Ford casting number I've ever seen. Checked my book and it listed the 1958 332/352FE with a EDC.

428 should be casted with a C8AE-F, or a C8OE-H for the 428CJ.

If you really want power from an FE, stick a 428 crank in a 427 block.

Uh...Those heads may be worth a little money to someone. They are early 1958 352 heads and came with the combustion chambers machined and a mechanical valvetrain.

If you want a fairly cheap and easy bolt on head, go EDELBROCK. It will save you a lot of trouble and/or money.

well if i had the money i would be using a 428 but i have little to spare. Why wouldn't using these heads be for me? also thoes E-brock aluminum heads for my motor are 1200.00 they would be nice if they were cheaper. i have already spent 1600.00 on machining and parts i should of just bought a crate motor. but help would be apreciated

[KULTULZ]

The heads will definitely work, but please be advised that they have smaller chamber volume than most later heads. This will affect your compression ratio (like I need to tell you that).

For a street engine (iron heads), you don't want much more than 9 to 1 or 9.5 to 1 CR at the most with today's fuel.

Also you say it has fresh soft seats. I would make sure it has (or have installed hard seats on the exhaust valves at the least.

I guess I am just getting old. It'd hard to see old performance equipment going to street use.

Let us know what you decide.

OOOOH!!
Those heads are old Edsel/406/early 352 heads!! You can very easily install CJ size valves in them and they have HUGE ports! Machined CC's are the giveaway. They are also the same casting as the early 406 HP heads!! They are the only "standard" FE head I have ever used where the intake ports actually used ALL of the intake gasket!! USE THEM!!!

I would have to go with Gary. They are probably more valuable to an early car owner that needs some. The machined combustion chambers are neat, but port technology grew in leaps and bounds through the early 60s and those didn't benefit from it. You can send some money having them posted to flow better, but then you've pretty much ruined the heads for a stock application. You would be better off with some later 390/360 heads. I haven't seen a pair of those heads since 1974 and I see a lot of FE parts. Those are 1958 era heads and the casting numbers I have for a 406 start with C2SE(C3AE on the '63), which is the first year it was produced. Those didn't come on a 406 from the factory. If I was doing the job you are, I'd drop some 428 valves in the 390 heads. The 30* intake seat helps low lift flow and the exhaust needs the larger valve. 2.09/1.66

These are not 428 probably a 360 trk engine it was manufactured in the 1980'd the letters C means 1060's....D letter means 1970's and yours is EDC E letter is 1980's

[kj6ko]

EDC was used on the first FE heads in the 1958 Edsel and many other Edsel and Continental parts. There were NO FE heads built in the '80s. EDC heads and other EDC FE engine parts are very early FE parts mainly used in the Edsel. The early Machine chamber EDC heads are very close in port size and CC volume to the first 406 heads, just with smaller valves. Like the guy said, they are probably worth more to someone looking for vintage parts than to someone looking to build a serious performance 428, but they will work very well!

One problem with most of those early heads with the machined combustion chamber is the angled spark plug threads have sharp points. you knock out the center of an old spark plug, screw it in then take the die grinder and smooth everything below the spark plug to remove those sharp points and round the edges . also removing some material around the exhaust valve helps. Those old thunderbird police interceptor specials were actually a 361 edsel (352 with 60 over pistons from the factory) installed in some fords.
