The valve seats are the biggest part of any head........the angles these are cut improve flow........as for lapping the valves or not, it depends on how they are cut. and then ground with a stone........todays machine shop have the best cutters nad stones to grind them with that lapping a vavle is a thing of the past.......if you have a otherwise good set of heads with one vavle leaking a little that one valve can be taken apart at home and hand lapped back in to help seal that cylinder back up.
to check this you need to have a motor together and leak each cylinder.......
Bring your heads down and have the shop due a quicky valve job........cheapest horsepower you can buy.

YOU WONT FEEL ANY DIFFERENCE AT ALL. EVERYTHING WORKS TOGETHER IN A MOTOR, CARB, INTAKE, CAM AND HEADS. YOU ARE VERY LIMITED BY RUNNING A QUAD WITH THAT INTAKE AND STOCK MANIFOLDS.

I will agree that you wont notice much of a differance, But I would put in the 1.6 exaust valves.........the exaust need to flow 80-85% of the intake to make good power and torque, the 2.02 would hurt you with the rules you have for intake and exaust manifolds..........But getting the exaust side of the head to flow a little better will help...........
It is a total package deal, I think the 1.6 exaust valves would make you a better package than you currently have.......Jeff
