Cam button install help
But just for reference, I set a lot of roller cams up like this using an AREngineering (preferred) or 440 Source aluminum timing covers.
I machine the ARP cam bolt heads down to clear the aluminum timing cover by .030-040" and the Comp Cams button to give .005-.008" clearance from the timing cover. There are other ways to do it, but this is my most often used method. I've tried to machine allen headed bolts down to size and found them too shallow and too soft to hold and the hex socket will strip out.
