You don't mention your exhaust system, so I will assume it is a good free flowing system. IMO, a cylinder head with a good exhaust to intake ratio like the Trick Flow, would benefit using a cam with less split in the duration between the lobes. The wider split durations favor a restrictive exhaust system, or a head with a less efficient exhaust side. I would personally call a cam grinder and have them make a recommendation based on your specific parameters. The cost is really not much more and it will be tailored to your needs. My W2 head 408 runs a hydraulic roller with a 4 degree split in the lobes. You may also consider tightening up the lobe separation angle, I assume these shelf cams are likely 110 degree LSA. I recommend taking the time to call a cam grinder like Mike Jones, or Jim Dowel. There is a lot to be learned from guys like that.
