I pulled the valve covers off, nothing obvious is jumping out at me. The push rods are straight and are not scuffed. I did have the passenger side rocker shaft installed incorrectly. I had the oil holes facing down but not facing the spring. doubt that was the source of my noise though.

I took off the stamped rockers and put the aluminum 1.6 ones back one with the 3/8 push rods. They have the same pre load set as when I removed them as I didn't touch the adjusters. I plan on starting over and adjusting them again, but after I installed it, it felt like some of the rockers were very tight side to side. Should there be some play? I shimmed it to get it as perfect on the valve stem as possible, and may have made them too tight. Could that cause the rockers to be noiser?
