flycutting depends on the cam and pistons. if the pistons are l92 style then you should be good to go (still depends on cam). any 4 bolt 90mm will work.you need to clearance the baffles in the passenger side valve cover to fit the offset rockers, unless you have really new valve covers. you need an ls3 coolant crossover line and the standard coolant plugs, i had the ls6 coolant crossover and bent it down to make the intake fit. you either need to extend your map sensor wires to fit the front of the intake or t it off the back of the intake.

you will need to flycut. who is assembling the block? if you are then you will need to install the cam, degree it, and then take it to the shop to have them flycut your pistons.
