Ok, small update time.
Those rocker arms were really hard to clean. There was a thick layer of coked on oil/carbon stuff on them. The parts washer solvent wasn't cutting it so I bought some oven cleaner at $2 a can. I ended up using 1.5 cans of the oven cleaner on the rocker arms. It was a process of spray, let soak, scrub, and then rinse and repeat. The shaft only took one go, the towers took about three, but the rocker arms themselves took about 8 cycles. I should have just had the machine shop hot tank them, oh well. They are clean enough to eat with now.
The 2f rocker assembly is on top as reference.
And here are the clean rocker arms. Much better.
I also picked up my camshaft and lifters. I am very happy with them, the were completed quickly and at a very fair price. It would have cost a lot more to have them ground by Delta. They were done by Interior Cam Supply LTD., the owner, Jim, is a very knowledgeable fellow. They are one of the largest aircraft cam grinders in North America and are a very reputable shop. This is a good option for us Canadians.
Here are the specs of the Cam, when compared to the Delta KC589 *262 cam they are very similar.
Duration @ 0.050: Interior Cam, 214 -Delta, 217
Cam rise: Interior Cam, .282 -Delta, .284
Lobe Separation: Interior Cam, 108* -Delta 108*
For reference, the Delta 250 S grind specs are:
Duration @ 0.050: 215
Cam rise: .255
Lobe Separation: 108*
I also bit the bullet and ordered a new cam gear after being convinced on here that mine was no good.

Oh well, better to do it right the first time than have to do it again.
