I run a PVC on one VC and a vent cap on the other. The PVC is plumbed to the port on the rear of my carb.

Most FE guys have a small hall in the top of their thermostat. Mine is about 3/16".

FEs in Cobras need burped. Air can get trapped in the top of the intake. Mine will work the air out with the nose of the car raised some. Alternately, you could remove the manifold plug or temp sending unit that is likely mounted on top of your intake near the front and let the air out.

A FE is a massive engine for the UK market. I am sure your friends are envious.

Half of my work team is in Derby. They all love to ride in my Cobra when they visit.
