valine to alanine example

I am trying to do the valine to alanine FEP example in the tutorials on the
AMBER website. I get the same delta G as on the web, when using the input
files provided, but the simulations are short, and various contributions are
not calculated. What is the actual "true" result (kcal/mol) for this
simulation? (has this been calculated in the literature previously)

I was also wondering if anyone has done this perturbation with the "PMF bond
contribution" (ncorc=1 and intprt=5, shake=3).

Any help would be greatly appreciated
