noisy roller rocker or lifter?

I have full roller rockers and they are noisy. Sounds like they are slightly out of adjustment tapping. It runs fine and I have adjusted at lest 15 times. Hot cold from 1/2 to 3/4 sound about the same. They are 1.5 trickflow on a hydro flat cam. Is it a dad lifter. Sound louder on one side but hard to tell. I am thinking of replacing with crane or comp in a 1.6. I have another post on that.

I have the 1.6 full rollers in my ZZ430. They have a reputation for being noisy. They deserve it ... Mine are factory OEM Chevrolet ones ... roller rockers are just noiser than the stamped everyday sheet metal rockers.

I have found that a stud girdle helps keep the roller rockers in better adjustment and also helps reduce the noise.

My sons 400 has a full roller setup and sounds like an old Singer sewing machine. Been told many times it's normal and not to worry about it, so we don't! LOL

I used steel-tipped roller rockers on my 454. They sounded like I had solid lifters. (I didn't)
I never got used to the noise.

I think that Deuce is probably correct.

Try adjusting them on the "ramp" just after the back side of the lobe. I have found several cam grinds that have had more clearance there then on the back side of the lobe.

Just food for thought.
