Thought on a magnum build

So was just curious peoples thoughts on this build. I'm sorts new to building my own engine as well. I have a 96 magnum, gonna send it off to get cleaned and have the cylinders honed. Crank will be stoked with KB167 pistons +5cc with .027 head gaskets, and a .509 lift cam 108 or 110 separation. And heads will be stock with light port smoothing and ill gasket match. High rise air gap intake and 650-700cfm carb. This is just to get the car driving so I can save for a 5.9 stroker kit. Thoughts? I'm hoping this will bump the CR up a bit...
