our shop is in Fairfield, CA so you can either drop the car by there or the head if you choose to remove it.
if the head is off or engine is out of the car i only charge $175 to drill the head..... is much easier that way and bits are less prone to breaking
i could travel to where you are and drill the head out of the car also for an additional fee.
as for USDM and JDM cylinder heads.... they are exactly the same except for the lack of EGR passages (JDM).... once the JDM head is drilled there is no difference at all
