From what I have read,with the stock valves in a stock LS1 head....it does clear....as long as the LSA is above 110.

no fly cutting needed with stock heads and valves. and MAKE SURE YOU HAVE GOOD VALVE SPRINGS! like the ones with the kit from TSP.

as long as your lsa is 111 and up if you are on stock heads then no flycutting. Make sure you have good dual springs, Patriot and PRC are what I use on my cars.

then you won't have to worry about flycutting. I would suggest going with the 112, gives you a little more clearance and it sounds better IMO.
