I am in the process of finishing a partly built Lancair 360.
The horizontal stabilizer is the standard smaller one. My question, is it worth it to cut it off and replace it with the newer one? How is the handling as compared to the newer stabilizer? Has anyone done it? And how difficult of a project is it going to be?<

Having flown both, it is not worth it provided:

A.      The existing small tail elevator hinge line is straight
B.      There is virtually no friction in the elevator control system
C.      The elevator bell crank has been shortened
D.      The elevator trim system is a geared system
E.      The trim/feel centering springs have been upgraded to stiffer  springs

Resale migh be better with the M-II tail due to perceptions.  The smaller
tail is reportedly a knot or two faster, lighter and all agree definitely
has no projected flutter problems.  The M-II tail may or may not require
additional BID stiffining of the aft fuselage/epenage depending upon whom
you believe to prevent flutter. Tough call.  Good luck.
