I'm not sure on the pushrods, it would depend on wether or not the hydrolic lifters are the same height as the solid lifters. If they are the same than the 170 push rods will work. The difference in the displacement is all in the block and crank so all things the same just swapping heads the 170 pushrods will work. If you goto slantsix.org there is a group buy on erson cams right now. Tell them your build and they will help you select a grind.
