Yes, vortecs have a normal umbrella style valve seal. Its never been an issue and your the first person I've heard complain about them failing so quickly. They are just normal small block heads like any other except the intake bolt pattern is different. That's literally it.

Just sharing a quick observation. When a cylinder isn't firing the ring pack doesn't work properly and crank case oil comes up past them into the cylinder. Have seen this on the dyno.
