I tried searching and couldn't find anything (maybe I was just looking for the wrong thing) but I had a question about the lines the run from the TB to the head, and to the intake to the top of the valve cover. To remove the hose from the intake to valve cover you just need to run a single hose from the TB to the head correct?

 

The intake to valve cover hose is probably the crankcase breather hose, unless you mean something else. It sucks gasses out of the camshaft area of the engine and has no coolant running through it. Why do you want to get rid of it? The coolant line running to the bottom of your TB should be for your Fast Idle Thermo Valve (FITV).

 

Leave it in place. The car won't run as well if you remove the line from the valve cover to the intake.
