Greetings, can anyone tell me on what year model Ford started using the rocker arm/roller followers with the smaller holes? We thought we saw a video that made us think our 2013 Expedition, 5.4L 3v SOHC should have shipped originally with the small hole version. However, when we pulled the valve cover we found them all to be the large hole version. (And #7 had escaped & was having a party jumping around in there...so we have pulled the cam & will be buying new innards this week to put it back together).
