Heads and cam swap

Currently, I am working on plans to get a 5.9 magnum in a 87 4wd, 5speed 3.54 geared dakota.
I already have converted the trans to the nv3500 , and have installed an electric fuel pump.
My next step is to find a 5.9 magnum, convert to a carb setup, (already have a holley 670 carb) and use a hei ignition.
Plan to disassemble the motor and hopefully only have to freshen up with bearings, rings, and gaskets.
In time, I would like to upgrade the cam and heads.
Now, to my question,
I wanted opinions on the following parts, and what kind of power you think it may make. Please keep in mind, I will have to use stock manifolds or no more then shorty headers. Love to have long tubes, but no way to fit on this truck.
This is the heads I was looking at. EQ Cylinder Heads for 5.2L/5.9L Magnum V8 - STAGE 1
And this is the cam. Camshaft - Stage 2 Regrind

I know this is an a body forum, but it seems that there are some of the most knowledgeable magnum engine people on here to ask.
Thanks for your help and opinions.
