[Healeys] 100/4 / A90 old style valve seals

[Harold Manifold]

I had head on my AH 3000 done recently and the engine shop highly
recommended the "top hat" style valve seals. If you are doing the head
yourself I would suggest taking a valve and the valve springs to a good
engine shop and they will be able to size the "top seal" and source them for
you.

Most mechanics favor modern 'top hat' style seals--I think they're one
piece--unless, of course, Concours Gold requires blue smoke from the
tailpipe.

By no means let crumbling rubber parts see the inside of an engine.
