Just as the title reads..

Whats the consensus of replacing the coolant crossover i.e. steam vent setup when re-doing heads?

I know there is an o-ring in the ends that you can replace, but supposedly pain in the *** to replace.

A new crossover assembly is like 40 bucks so not expensive in the grand scheme.

If I dont replace it and it leaks, it "appears" easy to replace after the fact or is this not really true?

I reused mine when swapping my heads. Been fine for 5 years and counting.

Same here.

No reason to touch it unless it leaks.

It's becoming the standard in recent years to add one to the rear vents.

Something to think about.

I'd suggest Sam@AMP in your area for the tune when your ready.

I'd suggest replacing it or at the very least, buy an extra one to have on hand. On two separate occasions I've had them break apart while reconnecting the hoses after doing something under the hood, despite looking perfectly fine beforehand.
