Default LS7 steam lines

Using LS7 crate motor in a mid-engine application (GT40). Using remote water pump, separate fill tank with cap that will be above motor's water level. This is my first experience with GM motors, and frankly, none of the local gear heads have any idea about steam lines (and basically all I know is they exist).

I have the hard line that can connect and vent both heads, and in the Z06, it would be front mounted because the engine is tilted with the front high (I think). My engine will be pretty much flat. Would you just pick an end and plumb them (front would be easiest)? Or get some of these and vent all 4 corners?

Thanks for helping a newb.

^^ Like said above, without the 3-5' pitch in a typical RWD vehicle you'll want to use all 4 holes. With a stock WP setup, you can run them either to the upper radiator hose or to the flat spot on top of the water pump by the upper hose outlet.
