Hi,

I have a 1989 Ford F-250 with the 460 EFI engine. We pulled the heads off the other weekend and sent them in for a valve job.

Apparently, the guy at the shop didn't know these where of a 460. When my friend picked them up, they got to discussing the situation. He said these heads were for another engine, but they should work on my 460.

The numbers are E7TE and 6090BD. Are these the casting numbers? If so, exactly what engine where they made for?

This engine was rebuilt at 30,000 miles ago by a guy in Florida. It has leaked oil and ran poorly ever since I got it. I've put about 10,000 miles it myself. All the valves where toast and somebody ground the old valves to make them fit this head.

Thanks in advance for any ideas on the casting numbers.

According to the article I'm looking at,E7TE casting # is for '87-'94 year EFI460 heads.Stock valve sizes should be 1.975" intake,1.65" exhaust.Ford offered a EFI429 engine in the medium duty trucks up until '98.A set of EFI429 heads might have similar casting # to EFI460 heads.That's the only thing I can think of....429 heads would fit a 460.

[updated:LAST EDITED ON 02-Oct-02 AT 01:44 AM (EST)]E7TE is an early FI castin # with it being a 87 or 88 head i think it can be associated with the 92cc combustin chamber, dont hold me to that though, i just remember that there were a few FI heads with the smaller CChambers. The exaust ports are horrible if you can or have the money and time port the heads extensively and install the latter 2.08I or go to a 2.20 and a 1.76 exaust valve combo the increase is worth it also ditch or port your exaust manifolds, those smog airports taking up a third of your exaaust flow are also robbing you of power. As to the motor being a tird, it might be an improper cam allowing too low of manifold pressure an RV cam will do this if the lift and durationa are too much. a leaky manifold might be a culprit too, speed density is easily irritated by a drop in manifold pressure and it tends to be a leading cause for poor performance in EFI motors.
