when dealing with rocker arms what is pedistal mount and stud mount, and what does my stock 87 302 have...

roundman

your stock 87 has pedestal mount rockers. this means there is a raised hump in the heads with a tapped and threaded hole in it that each rocker is bolted to with a bolt. with stud mounts, there is a stud screwed or press fit into the head and the rocker arm goes over the stud and is then held down with a nut. stud mounts are better for performance in the long run as you can install a stud girdle on them to stabilize the valve train but you can't do that with pedestal mounted rockers as there ain't nothing sticking up to mount the girdle to.
