Cams doubt

I always thought, all pieces in a customized engine should have a harmony and not all pieces can be "mixed". For example, X pistons with Y cams and Z flywheel could be a "bad working engine"...but with other combinations could be a powerful engine (i don't know if i'm explained)...this is true??

if I have to improvise an 16 now:

I'll take my 3 rib (oil consumed) furbished
high comp forged pistons ??
furbished and polished head with larger valves and springs (worked)
Cams and pulleys (with power midle rpm, not only in hight rpm)
Light flywheel ??
ECU

should i change something?....and i don't know what of those parts are better to get a powerful and usable engine.

change yes: skip the bigger valves - they aren't necessary until very close to 200hp and will loose torque below that power figure.
before you decide on pistons you need to decide on cams as they are interlinked. For your goals you most probably can get away with the OEM 10:1 pistons and a slightly thinner headgasket.

do both your block have internals? if yes measure them and compare the results with the manual to see if they are still in spec.

mixing parts in the 4AGE world works very well when done right, so you could take the 7rib block and 3rib internals (crank, rods, pistons) as long as all the clearances work out. Best case scenario is new rings, bearings and a light hone. But as said start with checking what you have and see what can be reused and what can't.
