Yes, you are. You should have 6 bakelite insulators, the same shape as the
gasket, about 3/8" thick (~9mm for the metric world :-).
They are fairly fragile and frequently crack when being removed from the
head.

I'd have to say no - they're there for a reason. At a guess I'd say they
provide some thermal insulation to keep the plenum chamber temperature down.
