Been following along... this is from the impala forum:
B-Body LT1: INT - 191º .418" EXH - 196º .430" LSA - 111º P/N 10243779

Not sure about the factory installed intake centerline, but assuming its 111 straight up I get the following at 050, with roughly +/- 25 degrees for lash points:

IVO @050: 111-191/2 = 15.5 ATDC (-25=9.5 BTDC@lash)
IVC @050: 111+191/2-180 = 26.5 ABDC (+25=51.5 ABDC@lash)

EVO @050: 111+196/2-180 = 29.0 BBDC (+25=54.0 BBDC@lash)
EVC @050: 111-196/2 = 13.0 BTDC (+25=12.0 ATDC@lash)

Hope this helps -
