Are you keeping the rods also? How much would you want for the pistons and rods?

Some of the vendors are selling L92 pistons, they should be the same. Otherwise call Diamond, I am sure they are making something.

Why do you need the cylinder length? All you should need is stroke, deck height, rod length, and deck clearance. You measure the deck height, and then plug in what stroke crank and rods you are using. The deck clearance is your choice and you figure the compression heigth from there.
amount the piston is in / out of the hole aka deck clearance = (1/2 x stroke + rod length + compression height) - deck height
I like a zero deck for a multitude of reasons... so
0 = 1/2 x 4 + 6.125 + x - 9.240 = 1.115 compression height.
