In the off road community, there are alot of quality engine builders/ suppliers (ie. CBM Motorsports, Turn Key, Redline, etc.) that practice the same method, even in their highend engines and sand rails (engines $20k+, sand rails $180k+)
I am sure that a stock application / system will produce less than acceptable results as compared to a custom aftermarket performance setup, like most of us run
Now back on topic for OP
I have had no issues running the VA heater valve in various installs
I have adopted the plumbing layout as done by Detroit Speed with regards to VA valve placement and converting the o-ring fittings to a "AN" style
here is a couple pics that I have saved and a video:
Hope this helps

That looks really clean. Are the VA valves failure prone?
