I was adjusting the valves on my 1954 235 6 cylinder. One of the adjustment screws was seized to the Locking nut so I bought a new one. The new one has a ball bearing on the end of the screw that I can compress. The other 11 do not. The engine has solid lifters. Could the one that I bought before hydraulic lifters? Can I use the new one if I adjust the valve so that there is no lash? Any help would be greatly appreciated. I have attached a photo of the original one on top with the one that I bought on the bottom

I don't know the part number. I installed it and set it at 006. Really noisy! I tightened it down so there was no Lash. Solid lifters in this engine . Really quiet and runs great. I'm chasing a noise that I thought was a valve problem. It's not. I think I've got some blow by problems.

Those adjusters are spring loaded inside. After ~70 years I would not trust spring tension and their reliability IMHO. I have no idea if they may cause damage to your pushrods or other drivetrain parts. If the seller/business lists them as 837385 or reproduction replacement for 837385 then I would ask for a refund.

Q-T Valve Screws circa 1953. Are they as advertised? Are they any good? If they were, we would have seen/heard more of them.
I would love to hear from anybody that has ever used these. Currently I only have one installed on one valve. I don't know how this would work with a setting of 018. 0.006 seem to work really well.

Why don't you contact some of the Portland Oregon area classic vehicle clubs. Maybe there would be someone who remembers the factory and can fill you in. Let us know if you find anything. All I could find is this old ad from the 1953 Popular Mechanics.
