Okay I'ma gonna tole yew! :smilie_happy: It's a very difficult complicated task. You need to remove the 1000 motor and bolt in the 1100 motor. Then you need to adapt the 1100 ignition or install the 1000 ignition on the left head. Not sure if there is any driveshaft change needed. That should be about it. :BigGrin:
Might be a few other wiring issues but nothing difficult.
