They are fitted between pairs of tappets. The springs are capped with plungers that contact a flat spot on the side of the tappet and help to prevent the tapped from rotating. If you ever disassemble a tappet rack, it will become evident how it all works.
It seems that the 1930 Durant 614 tappet racks do not have these springs, I just disassembled and reinstalled these tappet racks.
I decided to go the home grown route on the water pump so I obtained a new shaft and bushings from Phil Peters. I installed the bushings with a press and reamed with a piloted 5/8 ream, .625. The chrome shaft is .624. After hand reaming, I chucked the reamer in the lathe and power burnished the bushings for a minute or so.
The only problem I ran across was that the impeller was not drilled on center. The impeller pin hole in the old shaft was noticeably drilled off center. I aligned the new shaft hole in the impeller as best I could and ream drilled after alignment. The securing pin drove in tight and ought to hold OK.
Three pieces of 1/4" packing rope made for a nice seal and a fresh 1" expansion plug over the end of the shaft finished up the assembly. After a coat of black engine enamel, I'll mount the pump tomorrow.
Now, what do we use for water pump grease these days?

Got a few more things taken care of this last couple of weeks. I started to drain and refill the transmission when I found the input shaft extremely limber. This indicates, at least, a bad front bearing. I'll take care of that later. In the meantime, I used the already built tranny from my '27 Star project.
Now, I'll clean and relube the driveshaft and reinstall it.
I replaced the rear spring shackles with 35-42 Chrysler style and they turned out perfect. If I can find a set for the front springs, I'll replace those also.
Work has halted on the engine until I can get some parts from Uncle Gary later this month. I have a roadtrip planned after Thanksgiving to Gary's house and then to an undisclosed location for a pile of Star parts.

Shackles look good Don...The rubber bushing style will give you a firm quiet ride.
What did you end up doing with your front and rear crankshaft seals? On my W-6 I was able to do a little machine work and use a small block chevy seal (offset style), the front seal was already changed over to a lip seal.

I had a brand new rear seal assembly so I used that. The front felt seal was replaced by a Timken seal #471870. This was the only seal that would fit in the chain cover.
See pic, I carefully cut the spot welds on the felt seal retainer. That left a formed retainer that the Timken would fit snugly into. To secure the seal I spot welded three equal places on the new seal to keep it in place.
This seal is sized for a 2" shaft so the vibration balancer journal, which is 2.086" must be cut down to 2" on the lathe. This will give a perfect sealing surface for the new seal.
I can't believe I don't have a pic of the new seal installed. Anyways, anyone performing this modification will know how to orient the seal for proper operation.
The driveshaft universals are in great shape so a cleanup, beadblast, and repaint is all that is required.
I crawled under to lube all the brake linkages and found everything getting stuck or rusted so I'm pulling everything, beadblasting, painting, and relubing and trying to keep it all flying in the same order as original.
After 21 years of sitting idle, my joints would be getting a bit stiff too!
Could these springs be something in the pre 30 engines ? Not seeing anything in the US or Can aftermarkets for "tappet alignment plunger springs".
Just says to stop Valve Tappet Chatter, replace the tappet assembly. Very common trouble and only remedy to stop it is to replace entire value guide and tappet assembly.
