Hi All, So I got a "new" 350, and it came with a poston intake (when was the last year these were made?) and a 600cfm holley with a 1" spacer on it. I have a 750cfm Carter AFB carb and 1" spacer from the old engine that I'm going to switch onto it as the Holley is pretty dirty and would need a rebuild. Question is, what carb gaskets do you guys recommend for such a setup, what type of material, thickness, etc?
