Yes they do, some people run the 90# ones I think.

They run 90LB valve springs but I don't know for sure about rocker arms, they have 3rd gen that fit, but our bolts are 7/16" and LS1's are 3/8" I believe. Someone on here had theirs drilled and taped for 3/8". I have 1.7 Pro mag shaft mount roller rockers, the stock rockers are rated at 1.66 , so their pretty close.
