Calvin, you could also consider retarding your cam timing a little bit to improve mid/top end power. This is assuming you have sufficient exhaust valve-to-piston clearance.
Or at a later date, a bigger camshaft altogether maybe?
For a big engine like a 2.4 they seem to 'like' a wider lobe separation angle (112 degrees) than a typical 1.9/2.0 Opel engine (they do well with 108 degrees). You will also find that a 2.4 can handle a lot of duration, 245-250 degrees duration @.050" is not that radical for a big 2.4, and you'll need this much cam to make power to 7000 rpms or so.
