A little bit of history on this car, My father in law bought this car from original owner in 1972 with 74xxx on od. My wife went to Disney World with her brother in this car in 1976 for Bicentennial celebration and has very vivid memories of the trip. This car is a family heirloom that has been neglected for 35 years. Now I have the responsibility of bringing her back to her glory days. I have always been a Chevy guy and have built many show quality high performance chevys through my life but this FE ford is very unique and interesting. Thanks to all the members on this site for your help on this project and in general in the understanding of how this great classic should be built.

This car has bent so many pushrods it is unbelievable, how is this possible? I found that the valves were almost all glued shut and a couple of bent valve. I disassembled the heads, totally cleaned everything and replaced 2 bent valves. Painted the heads black and everything looks beautiful now.

When gasoline gets old it turns to varnish. That is what glued your valves shut. On a car that hasn't run for many years you should remove the rocker arms and tap on the valves with a rubber mallet. If it feels solid the valves are stuck. Shoot some carburetor cleaner down the valve stems. That usually does the trick.

I pulled the heads, disassembled everything and cleaned them up like new. Replaced 2 bent valves and lapped the valves. This being a 74+ truck engine it has hardened valve seats and everything looked good.

The bolt that goes into this hole is undercut:



The bolt heads look the same but one shoulder is smaller in diameter; one on each rocker shaft assembly. This ain't your run of the mill Chevy.

Yes I'm aware of the undercut bolt, thanks Dave. The restrictor jet is drilled out to .075, should help control oil to top and oil pressure down below. My next step is to measure valve train to be sure pushrod length is to spec. I don't want no more of this

Both ends of the FE rocker shafts are plugged and the only way for oil to exit is through the oil holes in the rocker arms.

I suggest you disassemble your rocker shafts and do a thorough cleaning of the shafts and rocker arms. Use a drill bit to clear the holes in the rocker arms. Use a Dremmel tool to better define the oil path on the inside of the rocker arms.

I cleaned and lubed them even though there was nothing to clean, they were like new. Some more progress made today. Rocker arm to valve clearance all within spec at .10 give or take a hundreth or 2 using standard length 9.62 in pushrods:D
