Why are you going to mill the block?
I think .020" off the heads is what I've read here for GT40's.
I wouldn't even fool with E7's, unless you are going to have them ported like crazy. (Thumper) Of course, you would be even further ahead if you were to port the crap out of some GT40's. Of course, at that point (if you are hiring the work and not doing it yourself), you could just call Jeg's/Summit and order a set of aftermarket heads that would prolly outflow either stock head, even if they are ported. Even if you don't have the $$$ for stuff like roller rockers and other hardware, you would still be further ahead. (You can always add rockers, cam, throttle body, MAF/injectors, etc on a Saturday afternoon.)
With that said (typed), I bought a pair of GT40's ($200) and am porting them, myself. I will prolly have another $100-$150 in the valve job. (Don't spare $$$ on the VJ.) I have to say that Thumper and others on Stangnet have been VERY helpful with pics and other tidbits of info to help me do it myself.
Go :SNSign:
I hope this helps. Good luck and keep us posted!

I agree with Paul about the P's 
Of course ... you got the header issue with them
Try and see if you can get a good idea of ........
how much money to get a set of P's ready to go
and
the same for a set of better flowing Aluminum After Market heads
Compare the difference in money between the two
and
judge for yourself if ..........
the additional money for the A A M heads justifies .........
the additional hp/tq gain
Won't cost you a dime to look at ... all ... options
You may find it would be beneficial to save a little longer
