should be a direct bolt on...
they are basically ls6 heads with slightly different valves i think.
should flow a little better than stock ls1 heads...but it will depend on the rest of the engine as to "how much" they gain you.
stock cam...maybe 10hp...bigger cam 15-20hp.

According to the GMPP catalog:
LS1, LS6 and LS2 heads will fit an LS1 and LS6 block
LS1, LS6, LS2, L92 and LS3 heads will fit an LS2, L92 and LS3 block.
LS1 / LS6 blocks are 3.89" bore
LS2 blocks are 4.00" bore
L92 / LS3 blocks are 4.065" bore
