The flywheel has five bolts and one dowel, so it is keyed to the crank.

The fan hub has a Woodruff key that keys it to the crank. The fan has three bolts and one dowel, so it is keyed to the fan hub. BUT--the molds for the fan castings themselves are multi-piece, and can evidently go together several ways!!! The TDC mark on my fan does not quite line up with the TDC notch on my flywheel. I asked around and found that it's the fans that seem to vary, not the flywheels.

Regardless, getting within a few degrees of TDC is fine.

Now for Ruddyboys' problem. You took the rocker assemblies off the head, yeah? If so, then there is a reasonable chance that the pushrods have not seated themselves into the lifters when you put it back together again. I found that, on my motor, I have to lift up the inner end of the pushrod to actually get it to seat into the cup in the lifter. If I do not, I run out of adjustment on the valve adjusters before they get in spec!

When the engine is in the car, I poke an L-shaped Allen wrench down the pushrod tube, bottom of the L to the inside. I use the bottom part there as a fulcrum, and push down a little on the outer end of the pushrod. That lets it slide into the lifter cup. Without that, you have about 1/4" longer pushrods, effectively, which eats up all your adjustment room and then some!!
