There could be a number of causes. Bad lifters and metal fatigue are two. I will post a link for you to read.

We changed the pushrod and lifters and looked over everything along putting back together and all looked great. Sat at a idel about 40 minutes sounded great went down the road heard a loud boom same as before and the ticking sound is back at a lose. Thanks for the post I appreciate your help just not sure what to do now

If this was my engine I would be considering a full valve train rebuild. Can't say this is what you need but I would be thinking about it.
