Hi Guys,
Remember a while back I posted about how my 94 F150 was running rough, poor performance etc, even after tuneups etc.

Final deicision is that we have a Valvetrain issue at hand here.
I had a compression test done, and the #6 Cylinder is only performing at 30% of the other cylinders. They then put oil in the #6 Chamber to see if compression would go up (for worn rings) and it did not move.

SO, I am faced with having to remove the head and take it to a machine shop to have them turn it around. My question is, has anyone removed and EFI Cylinder head, and how hard is it?

Thanks for all the help guys!!
