Setup looks good, what are your intended goals with it? Kinda hard to know where to improve it if you don't have a end goal.. Stealth heads ootb leave a lot on the table.. but are a pinch better than stock heads. If you have factory flat tops, better check piston to valve clearance if you haven't had it running.
It'll be making around 1hp per cube for sure but may be leaving power on the table with the ede carb.. My first motor build was similar but a smaller cam.. the new motor makes 460hp, but may make more with the new carb
If you're not concerned with handling leave the slant 6 torsion bars.. My Demon handles fine with them, and no sway bar. But it is setup as a stock interior street driven drag car with no cage.
If you're shooting for a street bruiser I'd install a Holley based 750, 3.55's or 3.73's, and 255/60 drag radials.. and you'll still struggle for traction.. but you'll still be able to drive down the highway for short bursts as well..
If you're remotely curious about my setup here it is.. can see pics in my build thread..

Machinist said I left about 40hp from the small cam, and I'm sure the unported intake left a few hp as well on the table.. but the sucker drives great, super quick, and just boils the drag radials thru 1st and most of 2nd gear hahaha
