Pre-Qualified or New Castings

Hi-Tech VisionTM Cylinder Heads feature Pre-Qualified Cores

Before any work begins, each cylinder head is inspected for cracks, damage threads and deck dimensions. Cylinder head cores that do not meet the Hi-Tech Vision standards are not used. For example, if the combustion chamber is cracked, it is replaced with a new casting. Hi-Tech does not weld-repair any cracked combustion chambers because the process increases the potential for both short and long term failures. To further insure like new performance and durability, Hi-Tech also installs 100% new valves in every head. With up to 15 hours of shop time required to replace a pair of heads, don’t take a chance by using or selling inferior quality product. Choose the No RiskTM Vision Cylinder Head by Hi-Tech.
