I recently bought crane cams link bar roller lifters for my 351w (1970 block). The instructions didn't say anything about re-using the pushrod guide plate but it seems to interfere with the link bars. These roller lifters are very expensive so I don't want to mess them up. A friend told me that these were the way to go instead of boring out the lifter holes and that I would get more top end because the lifters wouldn't float like flat tappet lifters do. Don't worry I just bolted in a new cam and put a steel gear on the dizzy.Should I use or lose the guide plate? Any help would be greatly appreciated.
