You can use Comp or Trickflow 5/16 x 7.400 inch moly push rods. Stock pushrods have been known to bend at higher RPm with higher spring pressure such as the yellow Z06 springs.

when i went through this debate, based off of old info i found posted by parish, among other, you just lose some preload. I did the swap, with 7.400 pushrods, no complaints here.

A cam with a smaller base circle then the cam used in the 5.3, is not gonna give you the advertised lift values of the ZO6 cam. I'm not saying it will be noticeable outside dyno testing, I'm just communicating what I found out while researching the best cam for my application. The longer sodium filled valves in a ZO6 make up the difference, to get the same lift value (.550) with a shorter valve you gonna need a longer pushrod.
