On my 80 Spitfire, there is nothing that prevents the cap being turned 180
degrees. There is an indentation on the cap to orient it, but nothing it has
to fit over on the body - until I added an advance.
Another possibility, if you had the wires off, you could have put them on 180
degrees off.
But as others have said make sure you have the number one cylinder at TDC.
