Carb base gasket question - picture

George,

That kit will work well. But you need to either fill your rod caps to make them flat on the inside or get some flat AFB/Edelbrock rod caps in order to run the Edelbrock primary rods/jets. The original AVS rods are longer and the original jets are taller then the Edelbrocks so the flat caps are needed.

Also, has the fuel pickup filter in the tank been changed? That can cause the carb to run lean if its restrictive.
