The measures are 6.025" and 1.615" for the Accel, 7.250" and 1.470" for the stock. My TB is stock 48mm and stock intake is ported (radiused) and matched.

Are they too much for my engine? Could my powercurve move too up and end up losing bottom end torque? The cam is set on zero-mark.

The problem you might find there, is the air thru the larger runners will hit the smaller opening of the intake manifold and cause reversion, which is bad for HP. If you can port-match your intake manifold to the runners, or get an Edelbrock or Accel intake, you'd be a lot better off.
