X2. When I 1st put my most recent 340 in the Swinger it sounded ticky as heck, but after a closer look it was just a header gasket leaking. Replaced them and now she is nice and quiet. Hydrolic roller should be quiet. Solid rollers tend to be a little or a lot ticky depending on lash adjustment. What brand rockers? I have seen some roller rockers that will tick no matter what you do. Hard to say. A video may help
