Two part castable silicone is your friend in this case.
You can use latex but its not as durable and can tear, the silicone can be stretched to something daft like 600% of its original length and still springs back.
I made sure the ports were clean and dry before using a little furniture wax sprayed down them, then seal the ports off with the valves and slowly pour the silicone in, let the air bubbles rise out, top it off and let it set.
It starts to go "green" ( just setting) after about an hour or so but its best to leave it 24 hours before removing it as itll have reached full set by then.
I just push it out steadily from the combustion face and et voila!
