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
