How noisy are Morel hydraulic roller lifters supposed to be on startup? Are they noisier in general than other brands?

On a cold start, mine are pretty noisy for a few seconds.

I have'em and yup they are noisy at dead cold start...what helped me with 'running noise' was, taking them down another 1/4 turn to 3/4 total. This was recommended to me by C Straub and the fact I have Iron heads.

If it is an aluminum headed engine you should have 3/4" to 1 full turn of preload. This usally will "fix" the issue.
