Research summitracing.com, jegs.com, eBay, craigslist, etc., for the prices of the parts. Plan on spending at least as much as what you come up with for parts to cover labor. Maybe more since you're doing a customized swap (in the shop's mind).

Parts of this combo are overkill.

350
11:1
185 cc AFR Eliminator heads
670 Holley Street Avenger
Edelbrock dual plane
xr282hr cam .510/.520 lift
about 450-460 hp

at 10.4 comp and vortech heads, that combo gave me 426 hp, and 436 lbs of torque. runs a lot stronger with the afr's

so you gained an extra 10 hp off the AFR's? do you think it's worth swapping from vortecs to the AFR's.
