i recently bought 3 brake caliper pistons from 2 different sources & brands & all 3 are a little taller then the original stock pistons, will this be a problem if i use them ? ( i need 2 more)

I don't think it will be a problem.... but that is guesswork.
I believe they are Z1 pistons.

i think you are right but they are advertised as h1 or s3 ...thanks

the ones that I bought, were 1mm taller than stock.
if you use new pads and use the shims; they are tight.
I cut 1mm from mine.

Don't always believe what aftermarket vendors say are correct applications.... I guess you already found that out.
The KH are the same as Z1.

they are 1.2mm taller , if i remove the alum ring spacer from behind the pad with the screw they work better....what purpose does that ring serve ???

Is this what you refer to?

If so, that is to reduce/eliminate brake squeal.

HVC caliper pistons are good. There is a variation among vendors for the height dimension on replacement aftermarket pistons.
