First problem your chip moduale says gm on it. You need an after market one. Stock one drops off at 5500 or so. If you dont already, buy a kit with recurve, moduale, coil, cap and rotor the works. Then google for hei setup usally you need to make several small adjustments for bigger cams. And usally all work toward restricting advace from mechanical and vacum and using more inital advance.
I wont go over all the steps here i have seen great stuff on the web for hei setups. With lots of good close up pix.
