crane 1.8:1 rocker arms

[u69038]

I want to get a set of Crane 1.8:1 "Quick Lift" rocker arms.
You can buy either just the rocker arms, or the rocker arms, push rods, guide plates, and studs as a kit. There is a $300 difference in price between the 2 options.
Is the kit realy required or will the stock studs and stuff work.
Thanks in advance

you have to have all the other pieces to make them work. the rockers are adjustable. they require the shorter 7.250 pushrods, screw-in-studs, poly locks, and guideplates.
