I'd just start another thread on that and I'd bet some of the top experts will comment on that! Just a hunch but they may tell you .040 is tight for BB and .055 may be the limit... Ask them though!
I am not an expert, but don't forget with an aluminum block and heads, you will get .010" growth, so the quench distance will grow as well...
You should have .061" after all ???? 
Good luck on the dyno!

the length of the sleeve doesn't change, therefore the quench will be the same.
As I said, I am no expert, but if the lash grows .010" how does that not increase the quench?
Please explain... 
Thanks,
Arnie
the lash grows because the head and block expand. the liner is not aluminum and won't change more than .001-.002 in length. the head is bolted down to the liner, which is typically above the deck anyway. if it's not, it should be.
in other words, the mass of aluminum above the deck will expand changing lash, but has little to no effect on quench since the head is still bolted down tight to the block and liner.
