Anyone have a sound clip of their Yella Terras roller rockers that they can post?
I'm want to compare how they sound in quieting the sewing machine sound to the Harland Sharp roller rockers.
Thanks,
Sleeper

Check this out after I re-torqued the rockers and seen where a couple of rockers were hitting and I filed a lil off those areas.
I used my stethoscope and there is more noise coming from the 30# injectors and under the LS6 intake than the valve train..so I think that is where the noise is coming from.

First is from when I installed the RS rockers.


Second is today after I re-torqued the HS rockers to 25 ftlbs and cleaned up some of the edges that the rockers were hitting.
