use Permatex Black "ultra" RTV on the front & rear china walls. Don't use the cork gaskets. I used the Edelbrock intake gaskets 7201. Use the included metal plates to block the center heat x over ports unless you are still using the stock heat riser choke on original carb

 

Typical,that seal at the back has to be installed just right or it'll leak.

 

The best way to install the front and rear valley seals is to throw them out. RTV is the only way to go, the seals like to squirt out and leak.
