But again, my goal is not maximum power. I just want more than stock power with a rock solid rotating assembly and valve train. I realize I'm getting very close, if not past, driveline parts breaking territory. But, I think with street tires and my driving style I'll probably be OK.

Unless you've already paid for parts, you might consider maximizing the combination as is. Especially if your driving style isn't hard on parts.
I did the same thing, and am now in a position that wanting more power means spending more on parts than had I just purchased what was best at the time.
Things like rockers don't change in cost across a 1.5 to 1.65 ratio, nor do the springs. But if you decide later on to change these things, you end up paying double, plus your time and labor.
At least something to think about.
My prediction for power would be in the 520hp/580 ft lbs range. I think the manifolds would work a bit better with a cam on a wider LSA. That said, this combo with an intake and header change down the road would likely pick up a good bit of power, even without a change in valvetrain package.
