Engine, LT headers w/ T5 install

Question about installing Engine, LT headers w/ T5 install

Hey guys, need someone with experience with installing engines LTs and 5 speeds
I'm intalling a 347 with LT headers.
I installed the engine and snaked the LT headers when the engine was 3/4 of the way in. The bell housing was on the engine . When the engine was set I bolted up the headers. Now I'm working under the car to install the T5 and I see the the headers could be a problem when I install the T5. (Headers could be in the way.)
Do any any of you have an order on how an engine is installed with LTs and tranny? Any help will be appreciated.
 
With the tranny in the car and the engine out, they are cake. The driver side one slips right in with no problems at all, and the passenger side one you put in before you put the engine in all the way. I litrelly had them on in less than 15 mins. Just don't even get 351 long tube swap headers, thats a different store :P
