Thread: How to Adjust Valves on FE 390

Tweet

Final torque spec on the rocker stands is 40-45 ft lbs. I slowly tighten them in the 1-2-3-4 order. Also be sure the necked down bolt on each side goes in the oil feed to head bolt hole. This is the bolt hole that has a dish and you'll see the oil feed hole inside. If you don't use the correct bolt there you will not feed oil to the rockers. So out of 8 rocker bolts 2 are necked down. 1 for each oil feed hole on the heads You might want to give the shafts and stands the once over. Sludge can buildup inside the rocker shafts and clog the oil holes. I also take this time to mic the ID of the rocker arms and OD of the shafts and check for wear. I check the springs and waver washers to be sure they have enough tension. Badly worn rockers can lead to over oiling in the heads. Also use the drainback shields that go under the rocker assy. For the record the aluminum rocker stands can be used in any order on the assy. They were all cast the same and all have the same opening to be used in the oil feed opening or other. The slotted hipo cast iron stands also have the same oil slot on the bottom of each stand. For the longest time I thought the aluminum and iron stands had a specific stand for the oil feed hole. But after comparing many sets to each other the oem cast and steel and stock cast aftermarket's were all the same.
