machine shope in chicago ?

I am in chicago, and I was curious how much a typical machine shop will charge if I bring them my b18c1 head and my new springs and retainers to replace them.

Also, what is a good machine shop around chicago that would do this for a good price ???

Opel in streamwood.

call up jc motorsports (630-499-5591) either you can probably send it to him and he'll have it done or he can tell you a good place i just went in there yesterday to check the place out hes doing a turbo for me great deal (greddy turbo kit, greddy blow off vavle,greddy profec e-01 boost controler/engine management, fuel pump, intercooled, and installed for 2600$ after taxes) this guy gets u damn good deals its all wholesale prices he just got back a sohc head for a civic he's workin on port polished new springs valves retainers everything looked like new.
