Modification Required:
•    For it to be “drop in” on a 12v 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. On a 24v you will need no more than .020″ 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
•    We always recommend new lifters when changing a cam. 


•    Pulling applications, Low rpm performance, Large or small singles or twins, desire for increased all around efficiency  


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.
•    Do not let the starter run for more than 10 seconds at a time
•    Once oil pressure has been verified, let the engine start and run for five minutes at 1200-1500rpm then shut engine down
•    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. Re-torqueing the head changes the valve lash setting, so it is important to set lash last
