coolant sludge everywhere..

I read coolant sludge is pretty common in our cars... Question i have is this suppose to be everywhere??? and this thick?
Im doing my H/C swap right now, replacing all gaskets.. will this help reduce sludge? ls1 how to recommends ls6 PCV conversion to help with this issue but can we go without? I got a little parionoid after seeing this, Im thinking i should replace all the hoses and start fresh... any ideas?

When Dex goes bad it's brown and looks more like mud. The color of this makes me think it's a little Dex mixed with some green or yellow stuff. I would replace all hoses just because their cheap and you might as well anyways, and then do some major flushing.

Check the power steering cooler and make sure it's not leaking into the coolant. I think that's what it looks like when it does.

How would i know if the Power sterring cooler is leaking? If im going to buy new hoses should i just get a new cooler as well?

Well, i hope thats what it is and not a mixture of oil from somewhere

Im pretty much going to replace all the hoses, find out how to check the PS cooler and go from there. Ive never seen this type of sludge before from my previous cars..
