Just came upon this thread and a couple of questions come to mind.
What is it you are expecting to get out of this motor? (How will it be used-track, street, combination...)
The 410 IS a "factory stroked" 390, so I tend to think the thoughts on boring concerns are spot on, but I feel the expence to stroke it vs. the benefit will be lost without investment in the "upper end" of the motor.
Personally, I would suggest going with upgrade heads, valvetrain ( including rockers which can be a weak point on these motors[see my gallery to see what can happen when the rocker shaft breaks  ) cam & intake.
It sounds like you are already going to bore .20 so you will be getting new pistons and you might as well go with an H-beam lighter/stronger rods at the same time. You already have a 428 crank.
good luck,
