trash the .093 lines for sure. Your not pushing the fuel or turning the rpms to need it. I also wouldnt go with the full cuts either. Yes they make power but are super dirty and create alot of heat. I would do away with the plate and do a good tuning job on the afc as well. With the injectors I would probably try some 5x.016's or some 5x.018's with some little tricks done to them or maybe trying a 7 hole designs.
What pump are you going to be running?
Get a good air dog and make sure it has plenty of fuel supplied to it.
No matter the tune in my opinion a 66 is going to be laggy on the street if you ask me.
Just my $.02

Especially on a P-pumped truck, a 66 is going to be laggy and dirty, the CR's can get away with it easier 
I would definately go with twins if you have the money, with probably a 62 or 63 mated to a 75.

I have ran the s300/s480 on my 24 valve but I didn't like the fact that even at fool spool they weren't that nice .. But maybe cuz of not enough tuning well have to see if my coin shines at the next paycheck

What was done to the 24v? The key to twins is tuning...
And just for my opinion which isnt worth much, a 66 doesnt work on a street truck especially with what you have down for a combo. Those full cuts along with a big laggy charger would result in HEAT! That is gonna be something your not gonna want on a street truck. There is more people on here with better knowledge than me but just trying to give my opinion.

afe magnum intake(air filter?)I didn't see anything in your list for guages.If you don't have those i would strongly recomend those.Especally an egt guage because you'll be increaing the fueling and the egt's will start rising.
