what are the cc size of the chambers on the heads??? whar is the thickness of the heads gaskets you are going to use?? the 9:1 compression u are wanting is really going to depend on what the heads are. That cam will work.
If you are serious about going with a SC be sure to buy a kit in pieces and not one from ATI. Buy the bracket and built setup/ tensioner from some one like SDCE with there spring tensioned 8 rib setup.
Then do a Front mount intercooler. A D1-SC will get you there if you can stop the built slip...... if not then step up to a F1 head unit.
Then the fuel system....... be sure to plan out all the details before the grand total of $$ sneaks up on you.....

while that cam isn't ideal, it will work. As stated above, buy your kit pieve by piece. Your heads are going to determine your final compression ratio. A D1-SC will work, but if you ever want to step the boost up (which you will 
) I would get the f1, either way you'll have a monster.

ok heads are 62cc with 204intake valve and 157 exhaust valve and are suppose to flow between 305-310 i dont know what thickness the hg will be yet but i will probably switch it to what ever will work best once i get my setup correct,cause the car will be N/A over the winter,how much does an f-1 go for?

1000rwhp if possible but for that what heads would you recommend?i will probably use my current h/c combo while the car is NA/ then sell them and get a better FI h/c combo

Yep, AFR heads, or if you're planning on waiting I hear GM is going to be releasing some new big boar heads that will flow near/equal to the LS7 heads, so you might just want to wait and see. As far as a new cam goes, FI cams are tricky to recommend, so I'll just say you're going to want less overlap, higher LSA.

IMO you should keep the ls6 and get a ported TB, the fast has been known to crack when put under a certain amount of boost, and the ohio boys are knocking on the 7 second door with an ls6 intake. If you use the AFR's you can keep the ls6 but if you use the 6.2L your probably gonna need to switch to the ls7/truck manifold.
