TDC, Power, exhaust, intake, compression,TDC power again. That is the order. If you have the intake on number one about to open your are rabbit ears down and 360 degrees off (at the crank, 180 at the cam)!

You need to remove the rocker arms on bank one, put the engine on TDC with the distributor pointing at number one, remove the cam bolt and gear, turn the cam 180 degrees till the other notch is up, reassemble. After you have done this the cam lobes will be rabbit ears up. Both lobes will have been off there valves for 90deg (cam rotation) and the next valve to open will be exhaust in 90 deg.

Because the only difference in these two conditions is when the spark occurs, no damage is done. Just don't try and turn the cam with the rockers in place at TDC.
