E8TE-DA 460 heads
i bought a 460 for my 86 and was going to swap it right in but i got a new DD so now im tearin it apart for a build, found i have E8TE-DA heads. are they about the same as the D3s? do they have actual hardend seats or are the induction hardend? and whats with the 88 part number but 5H19 date code?

Casting (not part) number: E8TE-DA = 5H19 = August (H) 19, 1995 (5).
But that does not mean these are 1995 heads, just when they were cast.
They could be service parts heads...sold at the parts counter, and could be 1988/89 EFI heads, or ?
Casting numbers cannot be cross referenced to actual Ford part numbers.

Actually IIRC those should be carbed motor home heads and should be the same as the D3VE heads (motor homes stayed carbed for a couple years after light duty PUs). IF that motor is a carb motor then I should be correct on it.

it is carbed and the valve covers that were on it were 86 non catalyst for heavy duty applications or something like that but im still lost on the date code being earlier than the casting number

Ok I got thinking about this while at work last night, take a closer look at that casting number I am betting it's actually E6TE but the 6 can be hard to distinguish from a 8 in the casting numbers.

i have looked at them and looked at them and they are clearly 8s there is a picture in my gallery and you can tell that it is definately an 8 and you can tell that the date code is a 5

Yeah it does look like an 8 for sure. If you pull them off take a wire brush to them though, not that it matters both the E6 and the E8 heads were supposedly for all intents and purposes identical to the D3VE heads, it's the E7TE and F3TE heads that are different and not interchangable

i just went back and reread number dummys post and i wasnt implying that they are 95 heads because if they were it would be fuel injected im pretty sure motor homes were fuel injected by then too i was implying that they were 85 heads with a 88 casting number becuase the valve covers that came off it were for an 86 heavy duty application, it has the 80s wireing and every other number works out to the 80s

E8 would be 88 which is why I think it actually probably is a dirty or smudged E6TE casting (possibly even E5TE both were used some) as that would match up with VC's etc but as he said they could actually be E8TE casting that was cast in 95 as a service replacements to be sold at a ford parts counter which would in fact make sense. That whole motor could actually be a reman or crate replacement motor.

E6TE-DA With flat top pistons?
I'm rebuilding my 460, looking at a pair of E6TE-DA heads because of the hardened ex. seats.
Can I assume these heads have the same combustion chamber volume as my old 73 heads? I want to run flat top pistons with a mild towing cam.
Not hot rodding this engine, just looking for a reliable, long lasting motor.
Thanks!

for all intents and purposes those are the same as your D3VE heads (right down to the fact that BOTH had hardened valve seats right up to the point you do the first valve job on them, then neither does unless you install them)

I didn't think anything gasoline got hardened seats until 1976

Actually since cats were put on cars after 1975 and all vehicles after then were required to use unleaded gas it would be 1975. But Cats were first used in 1973 on some cars.
And since D3VE heads were used clear into the 80s many many of them DID have hardened exhaust seats. But the point is still the same, do a valve job and you take out the induction hardened seat and need to replace it.
