    E5AE Heads

    E5AE

    Anyone know much about these heads? Might be doing a very low budget HO rebuild on my wagon motor this spring. I have most stuff other than E7 heads, however i do have these heads freshly rebuilt sitting in the garage. If they arent that much worse than E7's I'd rather use them and save a little money, plus get them out of the way. Just don't know a damn thing about them though, or if they are compatible with this build at all. No idea what they were even off of. Google didn't result in much other than some thoughts that the chambers might be too large.

    Flow wise, stock for stock they flow about the same as an E7TE casting. The chambers are a bit larger, so compression will be lower. Valve sizes are 1.76/1.44 I/E if I recall correctly, but then again, it's pretty early in the morning, so don't quote me on that just yet.

      chamber volume: 67.5cc-70.5cc
      valves:1.78int-1.46ex
      HO e7te(or e5te) castings:60.6cc-63.6cc
      same valves. IMHO, our e6 heads are better than E5A's. Hope you didn't spend a lot of money on those.....

        using a compression ratio formula for E7te headed ho mustang,we get 8.8 to 1. replacing the chamber values with E5A's gets us 8.2 to 1. then add in the fact that we have different pistons,and the number is probly closer to 8.1 to 1

            If they're freshly rebuilt and they cost you no money, I'd use them. The small drop in compression won't matter much.

                Thanks for the info. I'll keep an eye out for other heads for a decent price, but if i don't find any ill use these. They were free, and this motor doesn't need to be anything special. My main reason for rebuilding it is the fact that about every gasket and seal is bad. I do however have a lead on a pretty cheap explorer motor, i may use that or sell the parts for a little profit to pay for this. I'm trying to avoid messing with exhaust though and the explorer has p heads. i'll see as things go along....

                  I would disagree on that. Not that I'm trying to say the E5s are any great shakes, but the E6s flow so poorly that I'd still take the E5s over them. The E6s might give a small boost in compression, but it's small enough to not make much difference, plus if they don't flow well, there's not much in the cylinder to compress anyway.

                    Perhaps with the low CR, you can save up for a turbo from a four banger fox or Cougar and get some boost into that HO LOL.

                      The horribly shrouded valves on the E6 head really makes them suck. Apparently the raw flow data is close to what an E7 shows, but with that massive shrouding it really doesn't work well at higher air speeds (read RPM).
