I was told years ago to be very careful on selecting LSA on all 426 hemi motors due to the overlap affecting the intake and exhaust valves possibly hitting each other, I had one cam, customer furnished it and wanted to run it, which did that I had to have the valves cut down, narrow the O.D., and sink the seats also
108 to 112 should work fine on most grinds
Always degree the cam and check the valve to valve clearances with one piston out on the overlap Dang them Hemiroid motors anyways
