Building or rebuilding a VW air-cooled engine for your dune buggy? These EMPI chromoly head studs are exactly what you need for superior clamping force. The 8mm stock length version (part number 4020) is perfect for dual port heads and replaces OEM 043 198 035DP. What makes chromoly so good? It resists stretching and fatigue way better than standard studs, which means your heads stay properly sealed under all conditions. Each kit comes complete with hardened washers and hex nuts, so you've got everything you need for installation. The precision machining ensures consistent torque values and reliable performance. Whether you're running a stock engine or something with a bit more power, these studs provide that extra margin of safety and durability that can prevent blown head gaskets and other issues down the road. EMPI has been the go-to for VW performance parts for decades, and this stud set shows why - quality materials, proper engineering, and everything you need in one package.
