The definition of "best" here depends upon the kind of information you're looking for, of course, but in addition to the book by George Hopp that John mentioned (which is *very* hard to find these days) I would recommend the following as coming closest to being a "bible" on the '190 family:

For whatever it may be worth, here's a comparison of the Hurricane I and IIC noses according to the multiview drawings published in Modellers Datafile No. 2:
Although the relative proportions of the two noses shown here are essentially the same as those in the Aero Detail comparison above, the lower contours of the Mk. IIC nose strike me as more accurate in this drawing.
An interesting question; the answer is basically that although both wheel well shapes could be found on both subtypes, there are rules of thumb. The widely acknowledged definitive reference on this subject -- Messerschmitt Bf 109 F, G, & K Series, by Prien and Rodeike (Schiffer [uSA], 1993; 208 pages) -- states on page 15 that:
A large part of the F-2 series retained the squared-off wheel wells of the E-series. Others received circular wheelwells which were to become a characteristic feature of the F-series.
and on page 27 that:
The vast majority of F-4s were built with circular wheel wells, although here too there were exceptions.
Sorry, Guttorm, but I've been too busy downloading photos from this thread -- and too awestruck by them -- to offer any comments except these: "Thank you!" and "Please don't stop!"
