What manual valvebody for my 904?

I'm pretty sure it was rebuilt to high performance specs, its been a couple of years since it was done but I had it done with 12 second runs in mind. Now it may be quite a bit faster. I think I will invest in an input shaft and billet hub converter, as before I had it rebuilt I had cracked two converters in the hub area. I have the transmission out right now, as soon as I can pick it up (its at my moms in her garage lol). I got a B&M trans cooler, the biggest one they sell. Thanks for all the info everyone! Any more ideas would be appreciated!
