Engine build and installation guidance

Engine hardware must be matched to the exact engine version, machining specification, intended power level and complete rotating or valvetrain combination. Final clearances, fastener preparation, torque procedures, piston-to-valve clearance and calibration requirements remain the responsibility of the engine builder.

Do not order from the engine-family label alone. Confirm the supplier part number, required machining, included components and compatibility with the remaining short-block, cylinder-head and induction hardware.
