You could pull it out and get it welded. Most shops offer stock welded, stock with a modified neck to 3", or an all custom high flow unit if I remember correctly. I have a wherli fab fwiw.

^ X2 I was having the same issue with mine. I had Jason Wherli make a one piece high flow bridge. Problem solved!

Here are some pics of his fabrication skills.

I have the high flow kit from ProFab. It fits with the stock turbo. I have seen members here with this bridge and 4094s on their truck.

I thought about welding mine, I would rather use that as a last resort. Corey I am looking at the pro fab, that may be the way to go. Was it a kit ? or is the bridge and the boost tube seperate? I cany find a kit on the site for the LLY. Thanks all for the input. I have not ruled out a custom fab bridge also. I should have my truck back this week from the tranny swap. If I get off my ass and pick one I can throw it on this comming weekend.

Replace your clam shells with lbz ones and use the aftermarket y-bridge from a reputable seller. Better airflow is very good for the lly.
