Not much to pulling and reinstalling a VW engine. Only glitch over in a bug would be the dual carbs and the exhaust can get in the way. I'd think you'd want to add some bracing to the engine/trans support forks (Kafer bar/truss) to account for the extra power and swap out the old trans rubber mounts (to Rhino mounts) to new "while you're at it." You and a buddy with 2 6 packs could do in a day.
