i have no idea about the ls2's. im going from my ls6 motor to a 402 ls2 in my t/a and swaping over the cam which is a 240/244/112 lsa and was wondering what the best heads for a DD and still give good numbers?

i have trickflow 215's should i just put them on the ls2?

and what about the intake manifold? will the vengence ported fast 90 and NW 90mm TB work well on this ls2 or should i get something different?

now after that is all said and done i do have a tnt no2 kit on my ls6 and was still looking to use it. what HP shot would be safe on this motor if i have Compstar crank, Compstar rods, and Manley 2618 forged pistons (flat-top) with a nitrous/boost ring set?

what kind of numbers do you think this motor can handel up to? it is a short block from SDPC.
