option 1.
Exhaust, de-cat, induction kit and a remap will yield around 200 max. Not sure if manis will add any more from it, most likely increased torque.
option 2.
option 1 plus 270 cams will probably push it to 215/220 max with a remap but would you use them? Also would you find them plus the verniers?
I would go for the first option and fit a lightened flywheel, great fun
Then if you can find option two and happy to pay the money then go for it.
I think the majority know where we can take this engine with current parts, affordability and reliability. Anything is possible if you have the money, the know-how and the patience.
