Cam clearance

[97warrior_rider]

Hey fella's I know this is something some one has already covered somewhere and it has to be a simple explanation but does anyone know how to clearance a head to fit the mega cycle 252x1 .450 cam I've got the s1hc and the mega cycle 252x1 I wanna run the mega but haven't figured out the clearance issue which is starting to aggravate me if any one can help out I'd appreciate it.

The clearance issue is with the exhaust rocker arm and the valve cover. The reinforcement fin on the inside needs to be modified. I just dremeled the contact point down till it cleared and went a little farther one it did.

I used stock 05 raptor head, rockers. Kibble springs and retainers versa valves. I swapped that cam for a web .390-.430 cam
