emissions time!

i need to get my truck legalized asap. the thing is that i swapped out the motor for a 454. its a 1970 custom 1o. i live i Arizona and my current set up is a gen 5 454 with Eddie mani and Eddie 750 carb hei dizzy with spark plug gap set to .050. how many degrees would i set my ignition to try and pass? should set it to like 4 degrees to make the chambers run hotter in the chamber? would i pas with that carburetor since i cant adjust squat with the Eddie carb. would this be an issue?

Or,you could read all the suggestions and try those.It`s been well explained,I think,already.
