get the same cam, tighten up the LSA to around 109 advance the intake closeing about 2 degrees from where it was and run some 1.6 rockers, it will get significantly more power at every useable RPM.

2.5 dual and X pipe should boost power a little bit everywhere.

The performer only makes more TQ below the factory stall speed so don't bother with it, go for the performer RPM.
