Latest project with an explorer 5.0 engine

They used the tool, but they specifically told me when I went to pick up the heads that they couldnt get the seat pressure that they wanted using the tool. They shimmed them up to 100lbs on the seat. I figured that hey, they were a machine shop and should know if it would work or not so I just took them home and used them. Bad mistake as I already pointed out. Like I said, maybe it was just mine were a bad run or something.
