Studs come in 3/8 or 7/16 inch threads, pedestal bolts are 5/16 inch. I believe Crane cams has a retrofit kit with a 5/16 lower thread to mount in the head and a 3/8 stud for the rocker.
It's part number 36655-16 and summit has it for $120. You also need to make sure you have hardened pushrods too when you convert to guideplates. [ June 06, 2012, 11:21 AM: Message edited by: wilit ]
