looks as though those rockers are designed for stud mount.
The factory rockers are pedistal mount....so the answer is no they wont be a direct bolt on. yes with some machining and the installation of screw in rocker studs you can use these rockers but why?...when you can just go with a set of 1.7 cobra rockers...these will bolt down to your stock heads...the pass valve cover baffle with need to be modified to clear the new rockers.
changing out the stock springs would be a good idea too while in there.
