This is an excerpt from John Twist, I have not tried it but if anyone knows
MG's it is Mr Twist. Thomas, I'm sure you will find TDC with this method.
JOHN TWIST WRITES:
ENGINE: Check the valve timing: Set the #1 inlet valve to 0.055",not 0.013
(the correct
setting)(you noted .15 which is wrong by a
factor of two thousandths, or by a factor of
TEN). Then roll the engine around until
that #1 inlet snags the piece of paper you are
sliding between the rocker and valve stem --
in other words, the rocker has made contact
with the valve stem. The timing marks should
now sit EXACTLY at TDC.
END QUOTE
Thomas I re-read your original post. You
should be looking for the timing marks on the
pully that is attached to your crank shaf on
the front of the engine. You should be able
to see them from underneath your car (use jack
stands!).
Make sure once you determine TDC you mark it.

My 1970 MGB has no timing marks on the flywheel. I have tried several times
to align at the engine at TDC, but I cannot accurately line it up. I am
therefore unable to set the timing. Can anyone suggest a way to line
the engine up to TDC without taking the head/oilpan off?. My current
method is to stick a straw in the sparkplug hole, rotate the crankshaft,
and wait until the piston reaches the top of its travel. This method
does not provide enough accuracy. Suggestions are greately appreciated.
