Earlier heads are likely to produce 10-15bhp less. The maximum performance figures shown are based on using our components; we cannot confirm what your gains would be with non-SBD components. The results should be similar for the 2.0L & 2.3L Duratec, just produced at different rpm. Please refer to our kits for more information.
