I`m no expert but two things come to mind here.....1, those springs bet, the rockers bleed off too much oil and 2,HOPEFULLY your adjuster`s not showing that many threads below the rocker in that last photo.
All my adjusters have that many threads showing below the rocker.

Do not restrict the oil flow for aluminum on steel rocker systems. Period.

Just a couple of questions,
#1 does the motor have head studs? If so im sure the the stud itself is to big(1/2") and cutting off oil flow to the rockers..DAMHIK..the stock bolt is under cut to give room for the oil to pass and get oil to the rockers. Running the stud cut oil flow almost 80% over the stock bolt.
#2 Did you have the shafts on the right way, there is a front and a rear for the oil holes to line up...
#3 Are the effected rockers from the front or rear of the motor?
#4 Nice looking place you got there
1) No head studs
2) I didnt know there was a front and rear....I just thought that the rocker shaft oil holes should be facing down toward the head?
3) All the rockers on the driver side head had some damage ( I havent pulled the passenger side yet).
4)Thanks been in the new house for just over a year.
I think he was talking about rocker studs since the oil passage does not intersect a head bolt hole . you have bolts from the pic above , no issue there .
You have alot of open spring pressure for an unbushed rocker , but you need to confirm oil flow . I wouldn't do it bumping over the engine though , pull the dist. and run the pump by hand , be prepared for a mess .
Me , I would take an old junk steel cover , cut off the top , put the rocker shaft and rockers back on and see how much oil oozes out of the assembly once you get the cam in the right spot for the hit or miss oiling , using this method you could do it with the starter , deactivate the coil .
Hey, I am getting ready to test and see if I have enought oil getting to the rockers. I have a set of old steel rocker covers that I can cut the top off. How high should I leave the sides so that oil doesnt climb out and get all over the place?

How are the other cam bearings being fed oil?
Wow ... you're this deep into playing with a motor and you don't know how the oil system works!?! I think you're the root of all your problems. Start seeking advice BEFORE you spend money on the parts. I'm not trying to insult you, I'm speaking from experience!
Rockers are toast and the pushrods are too short. My guess is your problems won't end there.
The next $25 you spend should be on Andy Finkbeiner's book. Leave the motor alone until you've read it. It will give you much more insight into the problems you're having and how to resolve them. I'm guessing that you will quite likely get your rocker issues resolved on this thread but will only run into more problems elsewhere. Get the book, read it and hopefully it'll help identify other problem areas (if any) before you fire the thing up again.
As for the valve covers, leave as much of the sides as you can.

From the looks of things, lash caps would help or longer push rods 
No , not lash caps, his pushrods are too short.
Black , the oil from the oilpump goes to the up to the galley on the pass side of the engine , this galley has passages that feed each main bearing saddle to feed the crank and rods , from the main saddle there are passages that go to all the cam bearings , the #4 cam bearing has 3 holes , one on the bottom and 1 that goes to each head passage. The #4 cam journal has 3 holes in it and a Y shaped passage inside it, the holes are 120 degrees apart, as the cam rotates the passages line up and depending on where it's pointing it sends oil to one head or the other. hemi's have a groove in the #4 journal and I think the Y passage since they have 2 rocker shafts on each head and need more oil up top to fill them. Some people (as jamesc said) will groove the #4 journal and add restrictors so there is a fulltime oil supply to the rockers , bit not too much.
When you modify the BB oil system to increase flow to the CRANK it's said to restrict oil flow to all the cam journals except # 4 and the reason is because of the oil supply to the heads .
Stanton wouldn't it have been easier to answer the guys question instead of calling him a dolt ?

Great....how should the rocker/pushrod geometry look like? Here is a pic of the head and rockers installed.
You should have 2, no more than 3, threads of the adjuster showing under the rocker body

Mike i know you're one of the more experienced members here and i'm not arguing the point but from my experience when you groove the cam you do need to control the oil. i was told by a very experienced builder to use .060" orifices but thought i knew better and used .080". well the .080" just put too much oil up top and i ended up going with the .060". this was on b1 originals with the dove rockers. i guess there are a lot of variables but this was my experience. i certainly wouldn't even think about restricting the oil with the stock hit and miss system but in my case with a grooved cam restrictions were necessary. there's no doubt any rocker without bearings will fail if it doesn't get plenty of oil. i wouldn't try to run any of these rockers without full time oiling either by grooving the cam, bearing or external feeds like the indys.

Hello,
you said.
2) I didnt know there was a front and rear....I just thought that the rocker shaft oil holes should be facing down toward the head?
The oil holes should be down AND pointed towards the exhaust manifold.
Damon
You are Correct Damon 
From the pics it appears the shafts were installed correctly. As the wear marks are at the oil holes where the highest friction points would be.
To me it looks like a oil starvation issue on the rocker shaft galling.
The to short of pushrod is another issue that also needs addressed. mike

Stanton, You didn't use the word "Dolt"
But you did State"
"WOW... you're this deep into playing with a motor and you don't know how the oil system works!?!

That's pretty harsh IMO. You could of more easily and nicely answered the question like Johnhaha did instead of just stomping and pounding on the guy.
The energy/text spent would of been the same. One positive vs one negative.

Good to see I'm not the only one that noticed it ...
