[|GF|.:Kowalski:.]

Hi,
hope there is anybody to can help me out.
Maybe one of you guys can give me more details about the application and the performance of the 1.5 ratio Crane GoldAlu Rockers?
How is the quality? Informations about mfg failures? Maintenance?
please tell me the advantages and disadvantages of using stainless or aluminium rockers.

You didn't say what cam you are running (solid, hydraulic, lift, spring pressure), etc.

If you are running the stock Stealth springs (which I believe are made by Elgin), and the cam is a hydraulic "street performance" type cam, I would stick with the stock rocker assembly for durability and ease of maintenance.

If you have a solid cam, I would buy the Crane Iron rockers. (If you can find a good used set of the old Isky iron rockers, they are even better than the Cranes)

No Aluminum roller rocker will be as durable, and unless you are running extreme lift, or spring pressure, they are totally unnecessary and will be a step down in durability, and possibly performance.
