If the valve train is REALLY noisy, check for reduced oil flow. There is a passage in the head that can become clogged, or can become blocked by a migrating head gasket.

I went down that road, it's a waste of time when new INA lifters are $10 a pop.
And no, synthetic oil is not going fix worn out lifters.
