If the face of the rockers that contact the valve have not been refaced you will not get an accurate adjustment. The face is wider than the valve and gets a recess worn in it from the valve. The feeler gauge bridges this while adjusting giving a false setting.
This can make adjusting for quite operation imposable.
So how do I compensate for the recess without refacing the rockers when adjusting the valves?

Here are two videos of the valve sound from my '54 235 w/'59 head. Don't take them as correct. I have only adjusted solid lifter valves ONCE in my life. I believe that the first was made before I adjusted them (not sure.) The second was made after I adjusted them. They sound about the same as DADS50. I also have a "tick" like DADS50. Don't know if it a loose adjustment or something else.
