If it's eating iron and steel gears, then I would look to how it's installed on the distributor. There is a spec dimension on how the gear should be installed, you can't just line the holes back up and put the pin in.

Roller cams are either an austempered core, which requires an iron gear, or they're a steel core, which needs a steel gear, composite, etc.

x 2 on that. Take front cover off and check block to gear clearance.

On gears: I used to think that the Billet steel (mech & hyd roller) cams were alot harder than the "Cast" cams. But the opposit is the case. On billets you should use softer gears like composite or bronze.
On cast cams: steel/ iron gear. It has always worked for me.....?
