whats the difference between dished pistons and flat tops? what does it do too compression? what apps are each generally used for?
also, what does the bigger dish do say from -2cc to -12cc? im assuming for FI apps?

A dished piston is, well, dished. It has a negative impact on compression ratio, so it will be lower.
The dished pistons would be used for someone who would want to use forced induction on a vehicle. Or, maybe they are going to really be working it hard and don't need all the squeeze the flat tops offer.
so is there a rule of thumb for how many cc the dish is as in taking of points of compression?
when the time comes i want to do an ls3 or ls7 swap w/ a 200 shot and im assuming dish pistions are going to be needed.but im not sure how low i should go or what's recommended.

No, it all depends on what size the shortblock is. 1cc of combustion space will have way more impact on a 4.8L than a 7.0L.
As far as the dish goes, it all depends on what size shortblock you need. How about we discuss it in detail when you are ready to order. That way it will be fresh in your head.
so what parts come in your 408-415 package for a forced induction, like the brand of crank, rods, pistons, and are they forged or what. And what is the the whole gen 3 and gen 4 shortblock stuff all about
