1. Does the header tank (formally the overflow tank) have a pressurized cap or not?

Yes a 13 psi (or less) pressurized cap.

As long as the air can flow to the swirl tank's nipple un-impeded, it might work.

Is there no longer a "check valve" at the radiator? It looks like the radiator vent is just a straight hose to the header tank.

Did you use rubber hose, or a hard line of some type?

Thanks -

No check valve.

There was a factory 1/4" OD steel tube under the car for this purpose. I replaced mine with some new 1/4" OD stainless steel tube. I prefer to keep the sections of rubber hose as short as possible.
