I understand that I am just a stupid old guy with an advance degree in automative engineering. Thanks for exposing my ignorance.
Do they have those in automotive engineering as well? I think that would be more applicable in this instance.

Perhaps you didn't notice but they didn't just replace the head in that video.

WTF, are you just dense or what? AGAIN (!!!!!!!!!!) that 50+ HP they gained was NOT from just replacing the head as you said/implied. Of course a 4.0 can be built to gain 50+ HP but NOT from just replacing the head with an Edelbrock.In case you didn't notice they built the engine around the head. Oh by the way, in case you didn't notice they got more than 50hp.

Quoted in its entirety so you can't go back to change your original post to add more than just changing the head to make that 50 HP gain.Here is the ultimate solution to over heating and you get a 50 hp gain and better mpg. https://www.edelbrock.com/performer-jeep-4-0l-cylinder-head-50169.html.
And where did you come up with that "macrame artist" bullshit? Blaine is a well-known Jeep builder/designer.That is rich from a macrame artist.
If you are going to try and insult me, at least use the right word, it is macramé, not macrame.That is rich from a macrame artist.
Not to mention his profile shows his occupation as gambler, not engineer.Do they have those in automotive engineering as well? I think that would be more applicable in this instance.

No insult here, I have always admired a guy that could weave rope into a thing of beauty.

Sadly, I am not the one that does that. The best I can do is a few eye splices and a few of the basic Boy Scout knots. I pay folks who are better than I am to do the things I am not good at. You should see what the guy that writes my forum responses charges me.
Simply saying technology marches on, the Edelbrook head is an advancement in technology that can offer TJ owners path to more hp and efficiency.
Probably the only factual thing you've posted in this thread. I agree.

I like how you've been editing your posts after your argument gets destroyed. Nice. And your "66hp" worth of proof is compared to an older version of the 4.0, not the HO version that came in every single version of 6 banger TJ (which has an iron head). So even your 51hp gain was with an aftermarket performance cam, a header, roller rockers, no exhaust, a custom tune, no accessories......need I continue? I need to go back and look what rpm they ran it too also.
But back to the practicality or even theory of how it improves cooling........
I'm about 1/3 into my flush. Removed the thermostat, installed the Prestone backflush tee on the upper heater hose, flushed until clear with garden hose water, added Prestone Flush and drove it for a couple days.
That engine coolant drain plug looks to be a real PITA. How critical is it to remove and drain, and when exactly during the process should I remove it?
