No, only the alternator. No need to remove or open the power steering system. Once the water pump is off (along with the alternator) the bolts are easy to get at to remove the bracket and push it out of the way. I tied a string to it to hold it forward out of the way of working on the block.

If it's just a head swap...
The PS pump is bolted to the alternator bracket.The alt. bracket is secured to the head with 4 screws. Getting to the inner ones with the water pump in place is a PITA.
What to do, instead of draining coolant and removing the water pump, get everything else needed to remove the heads off (intake, headers, eyc), unbolt the head, lift the head up as far as you can off the block, then remove the alt. bracket from the head. The pump will stay attached to the bracket. No need to disconnect the PS lines, they have enough slack to unbolt and set the pump/bracket aside.

the plastic pulleys often are destroyed when removed from the pump, I've had them off without breaking, but seems they often crack
I'd remove the 4 15mm head bolts and disco the 2 lines to the rack(18mm flare wrench), remove the whole assy
pass side head: bolt for the wire harness
driver's side head: ground and AIR tube bracket(only loosen, notched fit)
ARP head studs and GM MLS gaskets for the install

Pull the water pump first, then suck the coolant out of the block, then pull the heads.
You don't have to pull the water pump, but be ready for a big mess to clean up (coolant in cylinders, on the floor, in the head bolt holes) and make sure you get absolutely all the coolant out of the bolt holes for the heads. I pumped my block dry through the water pump holes and only got a couple of drops of coolant that splashed over the exhaust side of the block when I lifted the heads.

Yes, but then try and get that pulley back on - I had to put a new pulley on my '01 - lucky the entire car was apart, cause it took an impact wrench and grade 8 bolts to push the new pulley on the power steering pump - it was a BI###### and then some.

head removal
Thanks to all
I unscrewed the three bolts from the bracket to the heads.I caught hell
with the ground wire and the ERG bolts in the rear.What is a good way to get the water out of the bolt holes.These head gaskets go on dry
or sealer around the the water jackets

LS1 Corvettes do not have EGR, that is the AIR injection pipe
cleaning the bolt holes of any material or coolant is critical
