I think you're gonna need more compression...
Most with the big numbers on the 402/408 are running 11.5-12:1....
The TFS heads "should" help you attain your number but I would be concerned with the area under curve as well as peak thus getting the car out of the hole.
I would just work the SCR/DCR up in conjunction with the cam and make that #!
Good luck!
