Carb gasket or restrictor plate?

I knew there was another reason, but I forgot what it was.

Yes, if anything the spacer lengthens the airway and tunes it for higher rpm. The "c" has a lot of torque anyway so lifting the carb gives a desirable effect and extends the torque range into higher rpms. I would leave it as is and plan on getting a new manifold and 4v carb.
