Welcome to the forums. I went through the samething at one point and it ended up being the rocker arms and rocker shafts were out of spec. The manual give you the service limit and mine were right at it. They would tap like crazy. Its also possible if you still are running the stock cam the auto decomp mech can be noisy. I was already running an aftermarket cam without it so i ruled that out on mine easy.
