OK this is very interesting to me. I have almost the same motor, and mine goes very well. Mine has bigger cams, but yours should go almost as well.
The difference is, mine can ONLY be driven at part throttle up to 3000rpm. And the power comes on strong from 3500 - 7000rpm. Plus it will freely rev to about 8000rpm, depending on the day.
Thie difference is cam timing. I have mine set roughly to 105 degrees on both intake and exhaust (home made degree wheel, not very accurate). This is very mild and has good torque and is very driveable. A standardish motor will have the cam timing set to about 110 degrees, torque will come on early but it won't rev. A more race orientated engine will have the timing closer to 100 degrees.
Your 288 degree cams with 34/74 timing, are set at 110 degrees.
(288/2) -34= 110
Reset the cam lobe centers to about 100 degrees (or 104 degrees if you want to try something conservative first). This will give you more overlap, and open the engine up for good rpm.
In your case this will be 44/64 timing for 100 degrees.
I'm not yet an expert on this, but this is the best info I have from what I have read, and seams to fit with my experience.
