Offenhauser intake

A few weeks ago I yanked my carb carter 625 and intake offy off cause the car sat for a long time before I got it. Gas was rotten and carb needed rebuilt. So I opted for a new intake and carb. Performer intake with a 600 cfm eddy. Anyways the car is running good now a little on the lean side but I was wondering if the intake that I pulled off is still a viable intake compared to the performer. Your thoughts are appreciated.
