Which stroker kit for 470" b-engine

I'm thinking I can make 600 hp with the RPM heads and maybe 650 hp with the TF heads. That is with 10.5 or 11:1 compression and a smallish solid roller cam.

To make that kind of power you need some fairly serious valve lift which gets a little tough to do with the 1.50 rocker arms. I think I can do it if I go with .700 lift but we'll see. PipeMax says it is possible.
