Default 4.7 engine noise tapping at startup

My engine has a serious engine tapping noise when I start it up but go away in about two minutes. Even when it goes away and I rev the engine and than take my foot off the pedal it sounds like a little rattling going on. I am thinking the lash adjusters bleed down while it is sitting. I am considering replacing them and am wondering if anyone has this noise and replaced the adjusters. It did not leave the factory with this problem so something has worn. Its a 2002 with 105000 miles on it.
