I acquired a modified head recently and it has roller rockers on it. It had the triple valve springs installed. I have removed them and installed the correct springs for the cam I am going to run. The pushrods that came with the head are longer than the stock pushrods.I plan on running a stock type lifter (hyd). Will the stock pushrods work with the roller rockers? Or will the longer pushrods work with the stock type lifter? I have not had any experience with roller rockers. Any feedback will be appreciated.
