Cylinder lid problems

Hello friends of mechanics, will anyone know? I have changed the camshaft of my Opel Vectra because it broke me, but the dumps with a presim Copy the valve, but they all fill up to the handle and step on my valves.

Thanks to those who answer those who read it.

What is not normal is that the valves are left on, if not that the arblol is different and the camshaft is greater ... Another thing is that the taques have been sponged with oil before mounting them, you will have to make them empty giving it by hand to the engine ... I do not think I need to touch the cylinder head (I have never seen to have to do it for a thing like this).
