i'm hearing both from the searches i've done apparently i had you get better hp with the flat top and better life out of the dished? what was stock? and what is best?

You should use flat top pistons with a head that has a .040" step in it. If the head doesn't have the step you should use dished pistons or add .040" shim under the cylinders to lower the compression.
