im swaping out my little 4.8l to a 5.3l
i already have the motor sitting on a engine stand at my shop
pretty much have most of the parts for it picked out already
now i just need some help on getting pushrods, valve springs and rocker arms
bought a cam for it which is a comp cam ls1 XR259HR-12 206/212 515,522
got comp cam hydraulic roller lifters
i want to get chromemoly pushrods but not sure the size i should get
also i need a recommendation on valve springs and rocker arms

thanks!
Brian
