Stroker low deck swap has started!

So I have a question for anyone with experience. Did y'all set the motor/trans on the k frame then drop the car on it? Then try and snake the headers in? Or option b is leave the k frame in the car and see if I can drop the motor/tranny in like the way the 360 came out. Prob have to pull the hood this time if I do it that way. I think this way would be easier to put the headers on cause I could adjust the difference between the block and frame.
