I bought the lt4 hot cam kit for my camaro years ago. Ever since I had it installed the valvetrain seemed to have a loud ticking sound. Recently I been having a high rpm miss. It seems like my valvetrain got louder. I can hear it with the hood closed and my car is very loud. Just wondering if those are supposed to be that loud.

 

It sounds like you need to readjust your rockers. They may have worked loose.
