There's another member on here who was talking to the guy who actually cast those parts and was talking about reproduction not too long ago.

Solves most problems, but can create others. Also most people already know about the First intake but are more interested in just runners alone. If they weren’t there wouldn’t be such hea solve most problems, most people already know about this better more interested in just runners alone. If they weren’t there wouldn’t be such heavy bidding on eBay for them when they show up. Some people just want to keep on their other parts and use their original throttlebody. I’m one of them. I will likely also use a different base. One that I will port myself. Otherwise absolutely this is not nearly as ideal as the first fuel injection intake you linked.
