So I need some light shed on this, I bought the header tank kit and heater bypass valve from my race shop and I see the pic of the system laid out but I have a few questions

1. Just making sure the heater core can be routed either way, no specific inlet or outlet flow
2. Which hoses get routed to the two small openings in the upper corner of the radiator then?
3. If you chose not to have a coolant resavoir (which I would like to do to clean up that front area) did you just run a drain tube down to the ground? If so how often does it discharge coolant?
4. Where did you install the header tank specifically (pics would be great)
5. Did you install the bypass valve and switch anywhere specific?

Thanks for any help! It'll help me make the most of the time I have in the garage
