I don't doubt your personal opinion of "looking like crap." Got pictures of what good and bad are in your opinion? Got a picture of that head's crappy intake?

3rd post with no hard evidence. Now devolving to an
ad hominem attack. When you point a finger at someone there are four more pointing back at you.
C'mon bro, keep it civil.
So before we devolve into a race to the bottom of the internet IQs, here's some evidence for you all to consider. Not the first time around this argument for me, as you will see below.
After a bit of time on google and forums this morning. I found next to nothing on google for 2016+ LT4's came up. If you take out the "2016 LT4" in quotes from the search you will get a mountain of scary pictures. Most of them of early 2010's GDI cars (BMW is notorious for this). But the only forum pictures I've seen on camaro or corvette forums of unmodified LT4 head intake runners have been fairly clean IMO.

One I found of a 2014 LT4 via google search was this:

TLDR: the word "spotless" was used in the post, daily driver, no catch can was used. Yes there's a picture.
"2016 LT4" head intake carbon buildup on google shows nothing.
A couple urls below containing 4 examples of corvette LT4 engines: Lots of irrelevant pictures, but a few of actual LT4 engines with relatively very clean valves. I say relatively to the other random photos of BMW, etc. engines from the early 2010's.

And the only pictures of a LT4 on this forum:

So after all this, in my opinion it is still not worth a) the expense and hassle of a catch can (OP's post), and b) voiding the warranty. If you go big HP or heavy in boost w/ mods, then sure add a CC to your build list. But for stock? no way.
Your mileage, as they say, may vary.
