Hello
What I know about Fords you could put in your ashtray. BUT you don't just put rockers in and tighten. Unless Ford had a better idea? You should get a manual on the engine there is a procedure for setting lifters be they hyd. or solid. They should be done in order and set to specks found in the manual or manufactures details. As far as the valley pan????? Sorry I don't know. I'm just trying to not let you get into trouble.
