For a 1954 235 is there an oil restrictor in the small line behind the side cover? I am not sure but i don't remember one when was torn down and reassembled. I engine ran for 30 minutes about 12 years ago while breaking in the cam. everything was oiling well with about 40 psi. The engine has not started since. the oil was drained and marvel mystery oil was added to the cylinders and rockers. turned it over by hand once in a while. I am removing all the chrome and stainless hardware. I will be reinstalling all the original equipment it came with.
I had to go back through your old posts to confirm what engine you have before offering info. It's been established that your block is a '54 235 Truck and the head was an earlier '53 casting, but still suitable for your block.
You can find the full '54 truck engine oil system description on these two pages Page 6-5 and Page 6-6 of the '54 Chevy Truck Shop Manual.
Nothing in there indicates there is a "restrictor" of any kind in the small oil line under the side cover.
Curious to know why you asked?

I believe there is a flow control orfice in the fitting back at the rear cam bearing passage, the one where the oil line to the cylinder head attaches. Try removing that fitting, and see if there's a 1/16" diameter hole in it. On the early rocker arm assemblies with the grooves inside the rocker arms inline with the weep hole at the top, controlling the oil flow to the rocker shafts is necessary. Later rockers with the offset oil grooves can run higher volume and pressure to the shafts. Jerry

The Block is a 1954 235, 3835911 and the head is 3836848 and I believe the head is 1960, A140. As I have been learning people could have mixed and matched parts to keep the old trucks running. Please take a look at the oil feed tube and rockers, looks like they are number 1, 2, L, and something like a diamond. There earlier engine's rockers are easy to read. This one is a little confusing, Is it possible that they may have after market parts. It's already ran to break in the cam. Just making sure before the test drive. It looks like someone pinched off the feed tube, and I am not sure if the rocker oil grooves are off set or even matter.
It looks like you have one of the later rocker oiling fittings. Check out this page. With that type of oiling fitting you should have rocker arms with the oil groove offset from the bleeder hole on top.
