Good morning all

I have a RV8 in a Luego and am at water plumbing stage. I'm after suggestions for the water circuit. I want to plumb a header tank and a heater matrix. I have the following connections to play with - top and bottom hose outlets (to and from rad presumably!) thermostat housing bypass (?) in and out on the back of the water pump housing (?) and an outlet stub on the back of the Edelbrock inlet manifold. My aim is to get the best out of the cooling and mininum airlock/flow/filling problems, so any suggestions on header tank and heater matrix plumbing/location and the general circuit plumbing would be appreciated.

Thanks
Simon

this is flow to and from water pump; it is with carb manifold.

for airlocks, on this manifold is a tiny tube that feeds to the radiator.

the small tubes from the pump are for the heater, one of them goes to the heater via the manifold.
