318 build check from you experts

Rebuilding the stock 318 in a D100 and using a bunch of leftover parts from my dart that got upgraded along the way. Wanted to get couple of opinions though on just what to do with it. The truck will be on the street 99% of the rest of its life. We are buttoning up the lowering job, new brakes and shocks and whatnot on it now. It was my high school truck and my son will be driving in a few years so I figure get it close to decent and drive it a bit, then he can work on it and upgrade as he can afford to. With that in mind, I'm keeping the 318 - mostly because I have it - and it will have plenty of power but be mild enough to not get him into too much trouble. I'm thinking some KB 9.5:1 pistons, it does have newly rebuilt stock heads but I'd be ok with putting some aluminum on there since now's the time to do. I do have a Comp 425 lift at 252 I can put in. Dont know if that's too much cam for the stock heads though. Will reuse an edel air gap intake and have a couple different 650 and 750 carbs, plus full MSD setup to use.

So I'm hoping you guys can help steer me on the cam/heads idea, what converter to look at (I have no idea what gears it has and the rear tires are 275/60/15's), and if anything is really standing out as a not workable combination. I figure if I go aluminum heads I could up the rocker ratio to 1.6's and increase the compression to 10:1 but then that cam may not be ideal... see where my head starts spinning...

Thoughts?
