1. Cost: The PCE261.1257 steel roller rocker arm set stud mount is more expensive than the factory aluminum rocker arms.

2. Noise: Some users have reported that the steel roller rocker arms can be louder than the stock aluminum ones due to increased valvetrain noise.

3. Potential Clearance Issues: Depending on the specific aftermarket components used, there may be clearance issues between the rocker arms and other parts, such as headers or intake manifolds.
