The old Crane and the Lunati are fairly docile but with a 3.23 they might be a good choice. Personally, I would not use anything less than 3.55 with a 4-spd bit your car your choice.
As for pistons, take a look at AutoTec http://racetecpistons.com/pages/autotec.php

If you want pricing or cannot find a local dealer then send a note through my website.
