LS2 Combo
Either AFR head (205 or 225) should be able to achieve that number easily. You'll just need a bit of compression to help out. In order to get the compression, you'll have to mill and run thinner gaskets, which will prolly give you P/V problems with that big of a cam.
I think you'll definitely need to replace the LS2 intake with a FAST to get there.

Yeah, I forgot about the FAST intake. The 90mm tb would help.
I figure 11.5 to 1 compression should be enough. Notched pistons should provide enough clearance.
I like the idea of running the 225 heads on a 4" bore. A 4" stroke would be nice but might not be worth the money.

With eagle cranks as affordable as they are, there isn't much reason not to stroke it. That is if the bottom end is being put together. If it is just a LS2 short block then you'll be looking at a good bit for assembally + the cost of the stroker kit. With SDPC selling the 402 short blocks for $3995, I'd go that route.
