Unless that is a dyno proven package there is no guarantee that the torque peak from that huge cam will match the torque peak from the large ports. OP will need to get it on the dyno and see what happens. If it is a dog then pull 10 degrees out of the cam and try it again. Of course, this might not be true for certain types of race cars. Some class guys run huge cams and spin the engine way past the torque peak just to squeeze the last bit of ET out of a combo. But the OP didn't appear to be building such a combination so I'm not sure what sort of advice to provide.
