Until I see proof for another option I will be doing this:

3L Short Block
2.5L Heads (Aggressive Port and Polish) with 3L
Valves
SVT or Custom Reground Cams
SVT LIM
SVT UIM
65MM TB

I feel that if you are going to build up a 3L, you my as well have your heads P&Ped to free up even more HP.. It will be worth it in the end...
