I've got my engine at a local builder and things just aren't going how I'd hoped. One of the hurdles is the rockers. He's trying to use these Chinese stainless rockers. Some look like they've been welded and ground. The caps on the rocker shaft are different width than the posts on the heads so the shims are only contacting on the head. ..Is this normal? Okay? If you had to get some rockers today what is a safe bet? I've been following this thread since it's inception and it seems like there still isn't a really good option but Crane golds will work? Any input will be appreciated. The engine is a 512 stroker flat tappet cam.
