Used Intake and Exhaust Valve

Hello FABO
I just bought a 4323302 head from Junk Yard. I was pull out from a 87 Dodge Ram150. It has stock 1.78" Intake and 1.50" Exhaust. I want to have machine shop to bore Intake to 1.88" and 1.60" for the Exhaust. Could I use "used 1.88" intake and 1.60" exhaust from a 360 head or I need to go for new one at $10 a pop?" What is the average price just for opening the intake and exhaust that include magnaflux the heads?

Thanks,
