Pulling Engine/Trans over the winter....Header Question??

All,
I'm planning on pulling the Engine/Trans together soon to get trans 100% and update a few things in the Engine compartment.
Question is - with the TTI Headers, will they be able to be left in place while I pull the Engine/trans out?
Years ago I'm pretty sure I remember pulling them out and leaving in the old Hooker Super Comps.
At almost 60 years old, I find myself doing as much research as I can to make things go smoother - this site is a God send for that!
Thanks in advance everyone!!

Wally.

Do you have an oversized aftermarket oil pan or a stock replacement center sump style?
On mine I have a 360 with a Milodon 7 quart oil pan. There was not enough room to get the engine and transmission in without getting stuck between the k-frame and the trans tunnel. I had to separate mine and do the engine from the top and then the trans from the bottom. Then once they were in place I have to lift the engine back up while connected to the transmission to get the left side header in place from the bottom.

I have smaller tubes than yours because I am using Doug's headers.

This would be a good time to start taking everything out the bottom on the k-frame. For me too next time, maybe. Although I am used to separating them.
