Default Intake Manifold Hoses

Im wrapping up my H/C swap and doing an LS6 intake as well. I didnt take any pics of where any of the hoses for steamer and PCV went and now Im struggling to put it all back together. I got aftermarket value covers so they are a little different but looking for some engine bay pics so I can piece this all back together. I have a service manual but the pics suck and are black and white. Specifically looking for PCV hose pics, the throttle body coolant line pics and where that connects and where does the steamer lines connect?

There are 2 lines that connect to the back of the intake. Size and purpose should be obvious based on the image below.

Thanks again. I got it figured out. PCV system is going to be more LS6 style because I have aftermarket valve covers and everything else in the engine is new except block, crank and pistons/CRs so why not. Waiting on LS6 valley cover to ship.

Well....I have yet to read anyone saying the juice was worth the squeeze on that mod....and you have to cut a piece out of the block to make it fit.

Cutting the block was super easy with a cutting wheel took 20 mins tops including the set up. I didnt really have a choice, I didnt have a simple way to balance the cylinder heads out with a vent for each valve cover in addition to a fresh intake line without cutting into my nice valve covers. I dont expect any gains from it but i need to have a PCV.
