Lift
The vertical travel distance of a intake or exhaust valve is called the lift. Valve timing and lift is critical for a properly running engine.
lift
The question is a little vague. So i hope i give the answer you were looking for. The vertical portion of the small diameter of the valve is called the stem. The vertical opening distance is called valve lift. The entire length of the valve would be the overall length. Hope this may help?
Exhaust fan is only use for exhaust the old air, while ventilation fan is use for both purpose intake and exhaust.
They are not exposed to as much heat.

Your exhaust lines up with exhaust pipes ,your intake lines up with your intake runners.
The exhaust lifters will line up with the exhaust manifolds,Remove the valve cover if your working on a V8 and the valve that lines up with the exhaust port will be the exhaust valve,If it is a Chevy V8 they will be from standing in front of the car exhaust,intake,intake,exhaust,exhaust,intake,intake,exhaust.
look at the head with the valve cover off find where the exhaust manifold goes in tha is the exhaust valve or looking at the valves the first one is exhaust then intake then intake ,exhaust,exhaust,intake,intake,exhaust if you have the head off i think the intake valves are bigger than the exhaust
-intake: exhaust closed, intake open -compression: exhaust closed, intake closed -combustion: exhaust closed, intake closed -exhaust: exhaust open, intake closed
the intake are next to the carb and the exhaust are next to the exhaust manafold intake are .008 exhaust are .012 with the engine warm good luck
Yes the intake and exhaust valves have to be close.
The intake valves are in the intake ports, the exhaust valves are in the exhaust ports.
Trace the runners. You can see the exhaust runners leading to the exhaust valves, and the intake runners leading to the intake valves.
