Notice they don't give a name brand for the rockers nor do they "boast" about what kinds of quality materials (specifically) they are made of, especially since they are serious racing pieces.
The materials to make quality rocker arms would cost about $100, and they are selling precision machined finished parts for that price? As a Toolmaker I can tell you these are Chinese crap. As for the guy that has had them in his engine for 3 years, this may be his year. On top of that how hard does he hammer it? I would never put these in my engine.
Notice the wonderful close-up pics. Too bad you cannot see the metallurgy in those pics. Can you tell 2024 from 6061 aluminum after it's been anodized? No, they both look beautiful.
Take a look at this, speaking of beautiful....

Isn't that a finely crafted ebay violin? I wouldn't hit my dog with that piece of crap. Yo Yo Ma himself couldn't that get that thing to sound like anything useful. "Beautiful" doesn't mean "worth a crap".
Stick to brands like Scorpion or Harland Sharp, they are American made with superior materials. Sometimes you even find them on ebay, or you win a set in a raffle at a car show, like I did. :banana: Got them for my 351 Cleveland for $10 in tickets.
