Default ls1-6 intake install pics please

I'm putting engine together that I didn't take apart and it's been years since I did one - does anyone have pics showing proper location of the bits and pieces that are mounted to intake? I'm getting ready to install engine in the car and don't want to figure it out when it's under the cowl later, I want this back 100% as it was made 99 Formula
thanks

it easy peasy then....be sure to use new intake gaskets.....consider the LS6 valley cover since the engine is out...recommend a new OPSU as they go bad or break in half ....there is a TQ sequence when TQ down....the fuel rail will push the injectors in the ports ...consider new O rings on the injectors

If it's been a long time since its run I would send the injectors out for cleaning. Install the oil pressure sender as it can be a bit of a pain to get at under the cowl.

the install of the manifold is not the deal, there are several brackets for various things that are bolted to the intake, i would like to see some pics so i can have them all installed in proper location so it can be installed and not have to be redone when its under the cowl.
did you read the initial post?
already has LS6 Valley cover

there are brackets on the PCV hose that plug into the mani at the bottom....slot looking brackets...same on drivers side for the EVAP canister
