Doug - The recomended part number for that spring set specifies a titanium retainer. According to Manley there is only one correct part number made by them for that spring set.
Again this why I am saying this was an error in part selection. Sorry if I was not clear the first time.
If I had stainless rockers I am sure that something more critical may have gotten broken, like maybe a valve dropping a head into the cylinder. As far as I'm concerned I was actually something worse did not occur requiring a far more expensive fix than waht i am looking at now.
Anyway you slice it an engine should not be breaking itself at less than 1500 street driven miles.
