T-56/BBC clutch options

[454SSguy]

So I'm getting ready to pick up my clutch kit this week. For info the setup is...

DAILY DRIVEN
Mark IV 454 (hoping for around 525-575 Tq @ rear wheels)
McLeod modular bellhousing
LS1 type T-56
Mcleod Billet flywheel

I'm looking into clutch options. The three I found are Spec, McLeod, and Centerforce. I don't have any experience with the 2nd and 3rd option, but I've had a spec stage 3 in my LS1 GTO (H/C/I + 250 shot).

Spec - Wasn't happy with clutch feel, and have heard bad reviews on some. Mine was ok, but it didn't get driven much.

McLeod - I'd like to do this setup to keep everything from one company but there super street is only rated to 500hp or less ($550), and the RST Twin disc is $900. I really can't do that right now, still over budget.

Centerforce - There Dual friction setup is around $358 for 11" kit and $415 for 12" kit. I read that the DF holds up to 700ftlbs. The prices of these are really hard to pass up.

Right now I'm leaning towards one of the Centerforce clutches, specifically the 11" Dual friction, it will handle everything I need it to it's rated @ 600ftlbs. I'd like to the 12" version (rated @ 700ftlbs) for extra security but I'm nervous about it not fitting in the McLeod bellhousing. I wanna stay away from the DFX b/c the wife will be driving the truck occasionally and she will complain about ANY chatter or tough clutch pedal. Sooo does anyone know if the 12" setup will fit in my b/h? If not I'm just gonna get the 11".

If anybody has any experience with any of these or advice on install or choosing a clutch please post up.
