I don't think the N2 aren't really a good fit for the T-storms.  They're a fairly mild cam, which makes those heads kinda overkill.  I think better choices for those heads would be N8, N4 or "bolt-in SE.  Keep in mind .500" is max lift for those heads with stock springs.

Run the N-8's @ 11.1 with the 883 trans sprocket. Should be at/near 90 hp.
