The flat head is about the only engine that the valves are not adjustable. Unless they have been changed to adjustable. You want TDC when NOT firing.
When you find TDC turn crankshaft 1/4 turn for each cylinder ,2 times for 8 cylinder.
Actually there quite a few v8 engines that fall into that category.Gm Ford and Chrysler.
