Labor in your area is probably similar but the last few that I built for customers averaged about $600 labor plus parts.

Bore and hone - 50
clean and prep - 50
press rods on/off pistons - 16
valve job and surface - 130
assemble - 350

BTW oem pistons/rings are about $325-350 a set

I would use forged pistons with N2O. If you add ARP bolts prepare to have the rods resized as well as the extra clamping force distorts the bore - add $15/rod plus parts. The stock rods with these bolts will handle plenty of spray as well as the crank.

I tend to avoid copper head gaskets in 99% of all applications as they leak and you need to make sure the coolant holes are set up right to avoid overheating. Stick with factory Honda/Acura parts as much as possible.
