I think Speed -Pro makes a piston like your looking for.
OP said he did not want the "heavy" L2404F (Speed Pro) pistons.
I could not find a weight on the L2404F - even on the Speed Pro site.
It looks like Diamond has a few similarily sized (dished) pistons available as Carl mentions, which are in the 586-668 weight range. What do the Speed Pros weigh?
