Default Chevy 350 hp?

I'v got a 350 bored 30 over. I'm curious what kind of power I should expect out of this. Here is what I'm running.
Speed Pro .10 domed piston
Std cast heads ported and polished
Comp camps x-treme marine 262 cam
Roller rockers
Stealth Intake
750 Edelbrock Carb

I'm hoping this combo gets in the the 350-375 range, any opinions on this?

Thanks-

Around 325-350 should be about right.

Even though I've had some work done to my old heads would I be better off with a set of vortec heads?

The vortec heads will not work with the .100 dome piston.

Right now I will be running the stock manifolds. I know I'm going to need aftermarket manifolds. What do you all suggest that are the best value?

Manley 6in H beam rods
Brodix Track 1 aluminum heads 2.08/1.60
Comp Cams Extreme Marine 270 hyd roller/beehive springs
