rockers

I have a la 360 with hyd lifters and stock rockers. My question if I go to 1.6 what can I expect for my money? Is it worth it? Will it give the cam any more rpms or what exacly are they doing for me? I also have eddy alluminum heads any recomendations on rockers?
Thanks Tom
For the HP you gain , not worth it . I changed to 1.6 because I needed new rockers , would no go and spend the $$ just for the small hp gain though .
