Bill....from an old "port grinders" standpoint, I don't see much to be gained
at the inlet port....unless the port is restricted or misaligned somehow, I just
don't see much gain there. In fact, I like the "open" port better.
Now, that doesn't mean I'm right.

Take a look at a 46AX. The crank inlet has a nice pocket machined to match very closely to the case, as compared to the straight cut you see on 46FX.
I am no engineer, but it can't be cheaper to machine that cut in the long run, must be some gain there going for , yes , no, ?
