Not much to gain with ported heads. Going with an 80mm pulley on the Mag will bring boost up from what I’ve seen. It’s good to go with an ATI balancer but don’t increase the pulley size since the 80mm upper will increase boost anyway. You’ll probably be at 16psi. On that SC that is a very safe level with no heat issues. You could go more boost but you will certainly run out of fuel.

I’m sure with your combo and don’t forget the low side fuel, you should be about 850whp.
