You might be referring to the TB heater line, which is a small coolant line that runs through the bottom of the TB. Its a coolant bypass to heat the TB in winter...which IS super common to delete.
Even if he does LS swaps for a living, I can tell you from the source, it is not a good idea to delete the steam lines on the heads, you need at least one. The cars usually had a front and a rear steam crossover.
If you ever got the motor hot enough to boil over, or it didn't have a place to vent, it will pocket the air in the highest point on the water jacket in the head. You can hotspot the head, increase chances of a blown HG, or risk cracking the head if its allowed to heat up that much and then rapidly cooled.
