Thanks for any help!

With a b cam and gt40 crate engine, you probably won't have any valve float.

+1, it'll spin it up to 6Gs without a problem, (if its all properly machined and put together right)

I have a 1999 gt40 crate with e303 cam and gt40x heads. No problem at all getting 6000 rpms before or after the supercharger was added.

B cam has pretty low lift. Should be fine
