As you mention, the cometic copper gasket is tied to the increased bore, but also, it's tied to increased durability over a MLS gasket with the boosted application.
Still doing some thought on colors and looks, but I'm think white or cream body work with a royal blue frame, swing arm, triple tree. Keeping the silver block and head, white or cream valve cover, royal blue foot peg rails and boards, silver forks, blue calipers, blue wheels, chrome like exhaust coating.
Going to try my hand at a render and see how I like it. Most of the waiting time will start once I get the motor torn down and shipped out to various places.
The heads going to get some special attention once cams and valve train are sorted, it'll be a unique variant.
I "may" go to single throttle body instead of itbs, thinking a 85+mm from an LS platform for simplicity.
