I am by no means a expert, but the E7TE head was introduced on the 225 HP 1987 EFI 5.0 HO so if that is the original head for the 85 it should make approx 25 hp less, since the 86 EFI 5.0 HO was 200 hp.
I assume there are date codes somewhere on the head or other codes that would confirm the origin of those heads. Of course someone could have swapped a set of E7TE heads on your 85 sometime in history for a nice power boost. With all the 5.0's running around with aftermarket heads stock E7TE's should be easy to find. ------------------ Frank W 90 5.0 LX Notch MAC 2.5"cat bk FMS alu ds, MSD coil, MAC shifter 2.73 gears user site 88 Notch 2.3L FOR SALE!
