When you got rid of the ABS, you eliminated any "proportioning"
of pressure.
The ABS modules have/had a "Combination Valve" mounted on them.
Depending upon the brake system; JB5/JB6/JB7/JB, the combination valve had a pressure value built into it that had a factory pressure rating matched to the model of rear brakes
I've used the Wilwood valves, they DO NOT "proportion" anything.
They are an adjustable "Flow Rate" valve, and they were designed for lighter weight vehicles that don't have much of a change in weight.
Not like a truck that might be empty,, or have a 1,000 lbs. or more in the back.
Of course you can lock-up the rears,, your brakes are now back in the old days of tech.
Your gonna have fun on a slippery surface,,, and if your in a bad accident you might have to explain to your insurence company,, or a judge about how you eliminated the factory safety system in the brakes.
So what is your suggestion to do instead of deleting abs?

The loops are engineered for a reason but it’s not for cooling. It is to accommodate the body of the truck flexing independently from the chassis.

I went with braided lines after failing to properly flair stainless hard lines...

To dial in the front rear bias you can swap some parts. There are 1", 1 1/16 and 1 3/16 rear wheel cylinders that will bolt in. I do think the earlier comment about the sliding pins on the front calipers is another good tip. It looks like you have the 1.25" master cylinder as you should for a 2500. I use one from the late 70's that is 1.125" might be a cheap option to lighten the pedal up a little.
