Many ported heads outperform off the shelf heads. LME, WCCH and LSD to name a few. Just need the hollow intake and Ferrara exhaust valves to get the most from them.Cant remember if porting those heads net any gains but something to talk with companies about.
So maybe port the heads
Race port on the blower
102 or 103mm throttle body
DDP Intake
Then you'll be maxed out on the blower where the only thing after that is a bigger unit or power adder like nitrous or meth.
Your pulley ratio is already at 3.60. (I would stay close to this) I believe from my reading 3.82 is max (using a 6,500 redline) so with your current combination, a 2.45 upper would put you right below that (3.76). Would increase you maybe 1 psi and be putting the blower at the MAX speed. You are close to sea level so that helps determine things as you arent being choked on altitude air.
These are just my opinion from reading. Use the search function to find what others have done or talked about.
The GM Performance LS9 CNC ported heads are ported already, but you mean they should be ported more? My first mod list was goung to be RPM 5" intake or DDP 4.5 intake and q 102 TB already since that was the least intrusive mods to start with.Many ported heads outperform off the shelf heads.

That’s not true, you don’t need hollow intakes on LSA heads, and some don’t recommend them with boosted applications.Many ported heads outperform off the shelf heads. LME, WCCH and LSD to name a few. Just need the hollow intake and Ferrara exhaust valves to get the most from them.
The hollow valves definitely been debated, however I am not aware of any failures in boosted spwcific applications. They are sodium filled and transfer heat better. The failures are typically tune or assembly related.That’s not true, you don’t need hollow intakes on LSA heads, and some don’t recommend them with boosted applications.
Many here are running WCCH heads with stainless solid intake valves, myself included.
I also don’t spin to 7k rpm because of many reasons, stock connecting rod bolts being one of them.

I was not debating with you. I just researched prior to making the decision to use hollow valves.I guess you would know better then me

Well, to be honest, I’ve spent probably over 100 hours talking with Richard and Dave at West Coast Cylinder Heads, for many many years, so I trust their input and experience.I was not debating with you. I just researched prior to making the decision to use hollow valves.
