If your having problems with the top end i would inpect the oil ways on the head, and remove the lifters and soak them in some petrol or thinners, you'll find the oil inside seeps after not very long

While they are out inspect the faces for pitting and dishing etc. Ideally if they are in good condition they will be completely flat. And also if they don't want to pull out of the head easy leave them be and get back to me!

Yea! Because the cam lobe is pushing it up, and the valve spring is greater than the pressure of the spring within the lifter, As soon as u start the engine the oil pressure will return it to normal.

Unlikely there is any significant wear on the cam or lifters then.
If the lifters were dished or worn it would be obvious, when they are ok they look very flat and highly polished in appeareance

As i said its best to stand them on a cloth after somewhere warm for a few hours, you will find more seeps out and you wont want to mix whatever you've soeaked them in with your engine oil
