Default Help with a stroker...

Ok guys, I was looking at buying a 403 ls2 stroker this weekend and would like to know a few things. The 403 has some pretty good parts in it, Such as Diamond -2cc Flat top forged pistons, Forged Compstar rods with ARP2000 rod bolts, and a K1 Crankshaft (Forged) all from Speed Inc. Now it also has a 248/254 614/620 110 lsa camshaft in it and Patriot dual valvesprings with retainers (.650 lift) Also a SLP Oil Pump and an ASP underdrive pulley
The induction part of it includes an LS6 Intake 42 LB SVO Green Top Injectors, stock TB, & Nasty Performance Polished Fuel Rails
The exhaust is PS LT's with 3" Rumbler X True Duals from TSP!
The kicker is..... The fact that it has STOCK 243 heads on it.
So with this in mind, How much power would I be looking at with this combo in my 98 Z28 with an Automatic Trans., 4000 stall, and 3.42 gears and the heads being stock. Obviously they would be a restriction, but how much power would I be sacrificing by running these heads until I get the rest of my setup together.
I basically just want the car to run mid to low 11's with the 243 ls6 heads and then I'll upgrade to the AFR or TFS Heads later down the road. Does that sound possible with that setup???
Any advice is appreciated. Thanks in advance...

James
