Are there really that many people interested in retaining the stock appearing intake after going this route?

One problem is that people expect to pay mass-production prices for low-quantity items 
This is kind of what happened with Black Top Racing; they used to make a cool starship Enterprise intake (very labour-intensive)... then they went to taking a cut on reselling off the shelf LED bulbs.

You shouldn't go into a project like this focusing on some direct monetary gain.
The payback is in having fun learning new skills, and possibly having a part that you could use for yourself.
If you can sell a few copies at the end to cover some costs, that's just a bonus.
I actually have a work colleague (well, he's not an employee, he's a freelancer), and he only takes on work that he finds personally interesting or useful. This helps him to remain motivated to bring his projects to completion. He doesn't live rich this way, but he does makes a living.
Of course, anyone who wants to make it big should perhaps not listen to my blabbering... I'm not loaded.[This message has been edited by pmbrunelle (edited 04-17-2020).]

That's the way I see it!

agreed, the BTR intake had potential, but was too complicated of a design to be viable at the price point they needed to sell them at to have enough volume to be worthwhile.

I 100% agree here too, my comments weren't meant to imply that it shouldn't be done because there's no money involved, more just to ensure that it's understood that it won't be a monetarily profitable item to produce, unless you have all the tools, materials, and skills, and consider your time free.

this is tricky, for a part this complicated, I think you would be hard pressed to pay for yours via sales to others, I've tried a couple of times with much simpler, easier to produce parts and the problem I ran into, that this would also run into, is the market. the The general populace of Fiero owners doesn't want a new intake for their 2.8, they want a 3800SC, an LS4, or some more modern, more powerful engine, so your already small market, just shrank even smaller, probably by more than 98%, so to cover your expenses, you end up having to charge more, and then you lose even more of your market.

this is why I don't design parts for the iron head engines, despite being asked about it on more than one occasion. I don't find most of the ideas useful or interesting enough for me to put the required time and effort in, when the same effort can be put towards another engine, that is already better than a 2.8.
all that being said, I encourage anyone interested in making a custom intake, to hit the books, do the math, get the torches out, and do it. post your plan, listen to criticism, take feed back, and post the results.

That's it right there, the common denominator of why a lot of intake designs don't work; they weren't made with applied physics principles.
These are my reference books, and along with some online calculator so I can verify my math. I'm not as bright as ericjon and Will you know!

I'm no genius I've just spent too much time learning things the hard way to keep screwing myself out of the easy way, IE, 14 page build spanning 7 years, and I'm not driving the car right now... Opening a book, and doing a little research before tearing into a new project pays off big time. The Army has a phrase(or at least I think it's an Army phrase), that I have begun to employ on more and more of my projects, it's the 7 P's
Proper Prior Planning Prevents Piss Poor Performance.
it really can't be emphasized enough, that and having a plan, is only worth anything if you stick to it. start with a goal, set milestones, give yourself deadlines, and follow through, only deviate if absolutely required, or your project can snowball into an absolute monster that never gets finished, or you never realize the results.

What I do is also cut back the inner all of these ports a few mm. Basically to about half the thickness you see on the inner edge of the ports. I do this to the middle intake as well. You'll have to use a razor to cut the gasket to match it. This is a substitute for not shaving down the lower part of the upper intake and the upper part of the middle intake.
you can see here what I mean:
It also lets you polish around those areas more...
Also, don't forget to port those heads...
