I ain't reading ten pages of this, and I'm not sure how I missed this thread to begin with, but I knew those rockers were Chinese as soon as I saw that Times New Roman font on the laser marked part numbers. The chicoms love that font.
It's probably already covered but:
The bushing material should not be oilite. Oilite has limp dick for compressive strength.
And the bushing material is ****. They've used some "it gold color, it bushing material" bullshit in there. Typical China Trash. You bought cheap, and supported communism, too. Sounds like it's working well for you.
I'm still trying to figure out why the hell you'd run stainless for a rocker arm. You afraid it's going to rust? Stainless doesn't have many alloys that have strength on par with carbon steel, and even then it costs more.
Now to submit my know it all answer and see how many people already posted this.
