the flycuts in the 4AGZE pistons are effectively a maximum depth, below the crown, of 4mm for the intakes, and about 3.5mm for the exhaust valve.
this is exactly the same for both the low and high compresison 4AGZE pistons, regardless of the dish depth.
someone else can check, but i think the 4AGZE piston comes up to roughly deck height.. so how far past the head surface do the valves protrude at max lift?? anyone want to check with a 20V head?
bottom ends balanced? as in the crank? or the rods and pistons??
fwiw, my 4K crank was well balance from factory (toyota does a good job with this), my pistons were within 1 gram (i made them 0.1gram), and rods were within 2 grams, total and end for end weight (again, made them to within 0.1gram) the TOSCO spec for racing 3K's was within 2grams...
if they did this on a 4K from the 70's, i imagine they do a slightly better job on all their more recent motors 
Cya, Stewart
