swap motor mounts while headers are in?

Hey fellas, I'm going to be dropping my trans to install my yank 3600 sometime next week. At the same time I'd like to put in some poly motor mounts and trans mount (shame on me for not thinking to do them while installing my headers). I was wondering since I'll have the trans out of the way and the car on a lift do you think I'll be able to unbolt them and push the motor up a little and finagle the mounts out to install the poly inserts? I really don't want to take my headers back out to just do mounts. I guess my other option is drop the whole k frame when I do the stall but I have no experience with that. First time for everything I guess though. Any thoughts?

You can do it without removing ANYTHING. Just have to be creative, use swivel sockets, and have patience. I did it to Call911's formula and it took me 4 hours start to finish taking my sweet time.

NICE thats a good sign.. I'll let yall know how it goes.

You'll probably have to unbolt the driver side header. Passenger side is pretty easy. Just take your time and don't tighten anything until all of the mounting bolts are started.
