Steve the F-20 guy

I am looking at 2 Heisler manifolds, both supposedly for an F-20. One has the number stamped on it HF 122, and the other has the number HF 122-L. Could anyone please tell me what the difference between them is supposed to be and are they both really made to fit on an F-20? The L version looks to have a little smaller exhaust manifold chamber on it if I am seeing it right, and the L has just a little smaller appearance, but I could be wrong about that. I sure would appreciate someone telling me what the differnce is if they would happen to know for sure. Thnx to any and all who respond.
