quick question

when setting top dead center are all the intake valves supposed to be all closed?
i been trying to set top dead center by aligning it to the marks on the block and head but the middle intake valve is down and i can see the piston but the rest are closed. i remember the intake valves all closed and lined up with the mark on the head and block before i rotated the motor manually. should i just go by what the lines on the head and block say?

When the marks on the cam and crank are aligned, number 1 cylinder will be at TDC and both of it's valves will closed. Valves on some other cylinders will be open or partially open.
