Cams doubt

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.

I'm noting it and learning a lot Thank you very much mates
I think will be better including to machine (hone?) the block and take new oversized pistons and i'll forget engine problems for a long time (...and more expensive)...not?
My 3rib was removed because it consumed oil, and my 7rib has a broken bearing...i think your advice is feasible
Like you and Oldsekewltoy said, increases compression with headgasket and machining head (i noted Oldsekewltoy's advice ".8mm TRD gasket, machine head surface .5mm")
I'm "lost" with the cam-pistons conbination... looking not to lose too much power in low rpm (an usable engine)
