Anyone know the rocker stud base size that will fit my 1968 Lincoln 460 heads? Planning on putting Comp Cams Pro Magnum roller rockers on it. Part #1330-16. I know I will need hardend pushrods and guideplates. I just cant find any info on what size the base of the bolt is. The rollers need 7/16" stud. Also what is the stock pushrod length? I have read I will have to get pushrods for a SCJ, since I will need a longer pushed with the roller rockers.

 

When I put threaded studs in my 1969 DoVE C heads for Harland Sharp roller rockers, the long length Ford units from Crane Cams were not long enough. I ended up getting BB Chevy studs that were long enough. They have worked out fine for me. JEGS technical help guys suggested that to me. Best of luck.
