E6SE Heads

Does anyone know the specs these heads? Are they worth porting/polishing? And are E7's better? Thanks.

E6SE heads are not worth the time. E7s are much better in terms of flow. Just remove the thermactor bump in the roof of the exhaust ports and you gain more flow. I have both sets of heads and went with the E7TE heads. Check out the head porting section, if you haven't already.

Part of the reason those heads are so bad is they have a heart shaped combustion chamber in which the intake valve is shrouded two thirds around. Very poor design for any kind of power,IMO.

They were used one year only, in 1986. The idea was to improve combustion efficiency by creating a lot of swirl. Nice idea, but it killed the flow, so they used the E7 heads from the truck parts bin instead from 1987 on.

That info is correct, but for Mustang only. The '87 LSC Lincolns still had the
200hp HO with the E6SE heads, as did all the standard, 150-155hp 5.0s in the Thunderbird('86-'88 ), Crown Vic('86-'91) etc.
