Remember that E85 is heavily subsidized so the cost is very low right now. Hope that production will be so much cheaper that it will be competitive price-wise with Race Gas once the gov't stops paying farmers to make that stuff.
This powerband from 6-9K looks delicious! Congrats!

If one looks at the specs for those cams:

There are two things that immediately come to attention. The first is the fact that these cams only give 218/216 deg of duration at 0.050", which is not ideally suited for high rpm power. Likewise, I see "106" indicated, which probably refers to LC (for both). This would be akin to setting HKS cams at +2/+2, and would explain why the torque peak occurs at a relatively tepid 6k rpm and tapers sharply thereafter.
If you have cam gears, setting them to something like -4/-4 would be immediately helpful. If not, just know that porting the heads AND installing a different cam set will deliver at least a 10% increase in power (and that is a conservative estimate) as sure as death and taxes. If you want to know how to get 700+whp, that's the ticket.
And oh yeah, invest in a good clutch. You'll need it!

Jasil is correct.
