Re: Anyone ever use this cam ?
Only need guide plates on stud mounted roller rockers.
The pedestals on stock rockers or bolt on rockers keep them aligned so these types don't need guideplates.
Yep, bolt on AOK for that cam, but if you have plans to go bigger later, then at a little more expense, you can get screw in studs fitted for stud mounted rockers & guideplates. Your choice though, but you'd be up for an extra $450 for machining, guide plates & screw in studs. Plus the hassel of pulling your heads apart in the process. Bolt ons avoid all that.
I think Yella Terra have a series that use a grub screw for alignment. Some guys here have them.
