Looks like great deal you got! Carbs will likely need more than just jets and floats. You'll want to scrub out all secret hidden passages. Ultrasonic soak and micro soda-blast everything. Be sure to get JIS screwdriver so you don't strip those float-bowl screws.
Feel this milkshake to see if it's slick. I suspect it may not be since oil+coolant mix from blown headgasket tends to separate into layers after a while.
