440 power gains/ aluminum head advantages?

i replied to fishmens67 with the main stuff i've done with tuning. watched and read a lot of things about what i need to look out for especially with a cam like this but im sure there's tons of little things ive looked over as far as tuning
If you have the distributor locked, I'm out. I don't have any experience with that, nor do I recommend it, so my advice would be pointless.
