Greetings fellows, I'm seeking advice on how to go about adjusting the valves in my 308 while the motor is out of my car. Can anyone walk me through the process or suggest a video? Thank you in advance!

    Take a look at Ken Cates website.  The engine section has an article on valve adjustment.  it is below the heading of Hudson Big 6

    You are welcome.

    It is available from the website previously recommended (which has great information).  I colored it so that the printout is easy to read under the car.

    I too have always adjusted valves after at  least a 20 mile run, so that whole assembly is thoroughly  hot and expanded.  Not with engine running though.  It only takes half an hour, and  it takes a few hours  for it to cool right down.   It is much more difficult on the Step-downs admittedly, as you have take the side plate off.   Do this beforehand.

    Its always puzzled me that in their workshop manuals Hudson specified hot valve clearances when most car makers specified cold clearances. 
    There is no way that on the Hudson engine assembly line the engines were run up to temperature prior to final setting of the valve clearances. The factory would have set the valves cold.
    Why inflict on your customers the hazards of setting the valves hot when Hudson didn't do that themselves?
