By doing the above items.
Does it require more changes internally or externally (tranny, clutch etc.) to handle more power? Other than the chest parts of cam, lifters, rods, possibly cam plate and oil pump, headers, exhaust I mentioned earlier?
Additionally, without getting specific. Are we talking under $1k, $1.5k or over $2k for the head work mentioned?
Further, what numbers (TQ/HP) would be ”reasonable” to expect from the above work as an increase from a stock 110 ?
Thanks for your time.

My testing has shown, on average you can expect at least 10/10 more hp/tq. Your results will vary based
on a plethora of factors. Mainly the cams, pipe and tune. But 10/10 is pretty typical if you're just doing head
work.
I did some testing a few years ago along these lines. We started with a couple mildly cammed bikes with stock heads.
Before and after dyno runs with very mild head work (pocket port and valve job) showed pretty significant gains
across the entire RPM range. They gained TQ all over the board and didn't lose anywhere. The bigger the motor, the
bigger the gains. I tested 80ci EVO, 95" TC and a 110 TC. All of them showed very similar gains. The 110 picked up
more than the smaller motors, but the before/after curves all looked similar.
