No, he missed a lot of detail which he found out the hard way and some that may eventually bite him.
Oil pouring out of the PCV hose..  We all know that you need the steel valley pan and a baffle under the PCV valve.  No brainer.
He didn't show any of the detail in regard to correcting oil flow through the timing gear.
He used a aftermarket timing cover. Hopefully he got lucky and has a good one.
In my opinion, he "fixed" oil passages that didn't need fixing.
I would have scrapped that crank and found a different one.
Also, calling it a street engine with 10.75:1 compression ratio is a stretch.  I guess he assumes that 110 octane fuel is easy to find.

It was a secret grind from Comp.

Interesting that the block was originally painted black and had the extra core plugs which dictates that it came out of a late Grand Wagoneer.  I pulled one apart that had the 5.9 embossment with less than 40K on it and it had the same wear on the thrust journal of the crank.  These were vehicles with automatics in them so we can't blame it on being a stick shift vehicle.

The aluminum heads would mitigate that to some extent wouldn't they?

I had a Mopar 383 with massive thrust wear, enough that the counterweights were striking the block. It was also an automatic and I couldn't understand the reason for all that wear. Block and crank scrapped. It was a dime-a-dozen engine at the time.

I am sure the aluminum heads would help but, how much I don't know.
I wonder if torque converter alignment has something to do with the excessive crank wear.
It could very well be oil starvation in the Wagoneer's case.  
Click on it to see a vid of excessive wear.
