That's pretty close to what I have. I'm using and Eagle rotating assembly, with SRP pistons. Rod clearances are exactly where they should be.

Still using the Dartp pro-1 heads, with some porting. My hydraulic roller cam is pretty big, with a lot of lift, and really makes cylinder pressure in the upper rpm ranges.

Dynamic compression is about 8.4. That works fine here at altitude. But at lower altitudes it's a problem. Since you live at sea level, I would shoot for about 8.4. It won't go up michy, and can easily go down.

On the chassis dyno, I'm making 510 hp.
