Not Ranked
For a 6500 peak on a solid roller for your application, I would use the Comp Cams Xtreme Energy lobes. They are aggressive enough for power, but not aggressive enough to cause valvetrain issues.
How efficient the cam is depends on how well the heads flow, so with a decent head, I would go with something like a 230/234 @ .050", 112 LSA, .561/.561" with a 1.7 RR.
Those lobes work really well but aren't spring eaters or valvetrain breakers.
I would personally rethink the Eagle bottom end and use the Scat crank and rods. Mahle makes a really light piston for this application that's already coated and has a thinner ring pack. Good stuff.
An aluminum flywheel works well with the road race applications, but keep in mind that an aluminum flywheel will make a high strung engine a little harder to drive on the street, and the result is having to slip the clutch more to get the car going.
