Re: 68 L71 Center Carb Base Gasket
You can not use the standard Holley 2300 base gaskets for our Tri-Power applications. Using a standard gasket or installing a gasket upside down will indeed result in a vacuum leak. These photos will clearly show the problem with the PCV port. Good news is that the 3 gaskets set should be available from virtually all the Corvette online suppliers.
