will I need to machine the vortec heads on my blue print L31 crate motor,when running this cam? How much more TQ. & HP should I expect?

You should not need to machine the heads, but you will want to check the valve spring coil bind. The TQ and HP will vary widely based on the rest of your engine setup.
