i would say centerforce duel friction clutch would be good.. but that will also depend on your horse power goals.

I've been using the Racing Beat heavy-duty clutch disc with an 8 lb. flywheel and stock pressure plate (would've preferred an RB street/strip pressure plate, but I didn't have one handy at the time). It's very easy to drive and grabs pretty well.

For what is worth I have heard good things about spec clutches.

9 pound aluminum flywheel, HD disc, street strip pressure plate. This setup takes me a few seconds to get used to it if I've driven something else recently. It feels like a light steel in weight because there is a Camden on the engine. The disc is grabby but also very easy to drive. The extra effort of the SS pressure plate is what takes a few seconds to get used to.

You probably won't like to drive it in bumper to bumper traffic. Fortunately your stock flywheel will take some of the abruptness out of it, making street driving possible. It's till gonna suck though... maybe.

You might try to look for a 6 puck. They're more streetable and still have high clamping force for the big boost numbers you're going to run.
