Description
G9U Cylinder Head Semi-Assembly – Valves Pre-Installed
This G9U cylinder head semi-assembly is a brand new, factory-fresh cylinder head built to OEM standards. It comes with the valve train components pre-installed, including intake and exhaust valves, valve springs, valve stem seals, spring seats and retainers. You simply transfer your existing camshafts, hydraulic lifters, rocker arms (if applicable) and external accessories from your old head – saving time and labour during installation.
