# 3803958 Cylinder Head Exch | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta remanufactured cylinder head for engines from serial number 1031804 to 10128117, weighing 103 kg and listed for one application in the TAD series. A Reman cylinder head comes ready for installation with valves and springs, and with the camshaft-bearing housings included where the design carries them. The serial range is what decides this order and should be read off the engine before anything else, because 3803974 at 105 kg is also a TAD head and only 2 kg separates the two. Volvo Penta lists this number as replaced by cylinder head 3801233 with effect from January 2026. That replacement is a new head rather than a remanufactured one, so an order against this number is most likely supplied as 3801233 - confirm which you are being quoted before ordering.
