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)
  • We always recommend new lifters when changing a cam.

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.
