- Valve springs are meant to prevent valve float and improve overall performance
- Heavy duty pushrods prevents loss in valve lift or retarded timing
Modification Required:
- On a 24 valve engines, you will need .018″ or less 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.
Applications:
- works great on 24v applications with 66mm or smaller charger for low rpm or with large singles at higher rpm.
- moderate singles, or set of compounds on 24v engines except vp-44 trucks, you will need a 178-208

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.
