rods and springs
 

i just bought a zo6 cam for my 5.3, should i also get the zo6 pushrods and valve spring or is there something else that i should get??

Kind of a small cam, I would get hardened pushrods and some ls6 springs.

If your gona buy new push rods, don't get Z06 ones, get 7.425 as a Z06 cam has a .050 smaller base circle (they make up for it with longer valves). You can use your stock push rods though (I did) . Also should get the LS6 valve springs. SDPC has them for like about $60 new :)
