Rebuilding a 302 from a 85 ?? Mustang for my Granddaughters 72 Bronco.....Noticed today that it has 2 different heads.....E5AE and E6AE. From what I can find the chambers are a different size. Any other major differences ?? I have a set of D8OE but don't know how they would do on a 85? roller motor...Or should I just find some E7TE heads and be done with it ?? Any input will be greatly appreciated..........

 

All those heads are junk.. either low compression smog era stuff(D8 and E5) or good ideas executed poorly(E6) so just go get some E7TEs or GT40s for higher compression and better air flow.

 

Thanks, that was what I thought..........Got my eye on a set if I don't get outbid..........
