Head different

Stefan,

The flanges are meant to be done up tight.  This causes the rubber boots to squash themselves to the insides of the port/inlet tube to seal the whole caboodle. 

Might be the one application that calls for that Hylomar goo... :D

My '73 3c had one of the socks already damaged from the factory, hadn't been inserted quite right and was squashed asymmetrically. I only pulled them out a couple of times, but I seem to remember greasing liberally with Vaseline petroleum jelly (no jokes about 120s, please, have some respect). Even the busted one seemed to seal, but how can you really be sure if you don't have a little leak?

Same as with any other type of induction system, Ken.

At idle, spray brake cleaner liberally over inlet stubs, head joint, etc.  if revs rise, you got a leak.
