I never hear much about guys replacing lifters when doing cam swaps in their LS engines...are the stock lifters roller tipped? Is it just over looked or are the stock types tough enough to support most of today's aftermarket cams? I'm considering wether or not to replace mine when I swap the cam...car only has 4700 miles on it so I don't think they are wore out yet

 

I just placed the same post eairlier, scroll down some and you will see it.
