Following up. A few weeks ago I took my car to Wil at Static Performance, as recommended by Paul. It took some back and forth with Wil to establish an appointment and from what I've heard from others, Wil isn't the easiest to get ahold of but texting or calling is typically one's best bet. It took about a week from when I first texted him "hey I'm ready and have all the parts required" until an appointment got set up. Typically texts to him would be in 'waves' with short bursts of communication then silence for four or five days or so. This got me kinda worried about his reliability.
Once I dropped the car off though, things went very smoothly. I took the car to him on a Tuesday (after a last minute rescheduling on my part) to have headers installed and my oil pan replaced. Wil was happy to show us around the shop for a bit and let us check out the cars he was working on. The location is a little hard to find (really unexpected to see such an elaborate setup off a dirt road) but feels hidden/secure. If your NSX is low, I highly recommend iLIFT to cover the last 50 feet or so to the garage. After talking story for a bit, we left Wil to his work and the next afternoon, he texted me to let me know the car was ready for pickup. Payment was in cash, I got my old parts back and Wil gave a quick report on what he found/saw while he was under the car.
My overall impression is that Wil is definitely a solid mechanic first and the businessman side of things is secondary to that. This is probably not a big deal to most of his customers but because the NSX is the only car both my wife and I have to use, I felt a little worried that I could not count on Wil. However once my NSX was dropped off, things went quickly and efficiently and I was happy with the service.
