Modification Required:
- For it to be “drop in” on a 12valve, you will need no more than .020″ piston protrusion and at least .055″ valve face depth with a standard head gasket and a 99 intake centerline. . If you do not meet the minimum requirements for piston to valve clearance, don’t worry, you can still run an oversize head gasket or cut valve reliefs.
- Although this is considered a drop in cam it is important to check clearances
