Buy or make a piston stop and screw it into the #1 plug hole. Rotate the crankshaft CW until the stop contacts the piston. Mark the position of the damper timing mark on the block. Now rotate the crank CCW until the stop hits the piston and again mark the position of the timing mark. The halfway point between the 2 marked points will show you where TDC is, and if it's not the 0- degree mark on the timing tab you know that either the tab and damper are mismatched or the damper's outer ring has slipped.
You can do this on either the compression stroke or the exhaust stroke as long as you remember which one you were on when it comes time to installing the distributor.
