The L model had the MFI but with E cams. IIRC the L model became the E model.
There is not a lot of difference between the original 911 cams, aka solex, and the E cams. The S cam is much more aggressive. When the T came out that cam was very docile.
Look here.

One other thing to consider when choosing an advance curve is the compression ratio. For example the S motors use less total advance.
