comp 918 beehive springs and comp hi tech 7.200 chromoly pushrods. you will be fine with stock lifters. you might have to ditch the rockers you have now and go with a non self aligning rocker because you wont have enough valve stem for the roller to sit on. i would use a set of nsa comp pro mags and guide plates
