Modification Required:

• For it to be “drop in” on a 12v you will need no more than .025? piston protrusion and at least .055? valve face depth with a standard head gasket and a 99 intake centerline. On a 98 – 02 24v you will need no more than .025? piston protrusion and at least .038? valve face depth with a standard gasket. On an 03 and up, it needs .018?piston protrusion and at least .038? valve face depth with a standard gasket.  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 (You can use our clearance calculator to make it a little easier)
• For the Steel version you will need atleast two bushings installed in the cam tunnel, otherwise the steel could eat into the cast iron block
• We always recommend new lifters when changing a cam.

Applications:

• Used in daily drivers
• hot street
• Drag strip
• Stock class pulling

Break in:

To make sure that you have no issues during break-in, follow these few suggestions.

• Make sure that the cam has a Liberal amount of quality assembly lube applied
• DO NOT let the engine start without oil pressure
• When this is a new engine, be sure to put a liberal amount of assembly lube in the oil pump and prime the oil filter
• Be sure to change the oil after you have done your break-in procedure. When the filter and oil system are already primed, engine will get oil pressure much faster than if the oil is changed at the same time.
• Disconnect the fuel system and spin the engine with the starter until oil pressure can be read or until oil is coming out of the rocker arms.
• Once oil pressure has been verified, let the engine start and run until up to operating temp
• Adjust valves then you are cleared to abuse your engine. Enjoy the added airflow
• if you need to re-torque or “hot-torque “the head, do so before adjusting valves. When you retorque the head, the valve lash setting, so it is important to set lash last.
