Valve Cover Gasket 403

[Bacchus403]

Hi guys, any idea where to source a valve cover gasket for a 403, or will I need to make one?
Thanks in advance.

Not sure about PUG but used O ring material that fitted in R16 tappet cover gasket groove & exposed enough to compress & seal.
Cut to length & joined using loctite 406.
Unfortunately can't remember the diameter but basically just made a big O ring.
